Lochend Loch was a post-glacial 'Kettle Hole' lying within a substantial depression and fed by the relatively minor flow of the Joppa Burn, field runoff and rainfall, its outflow running into the Water of Coyle as the Barwhey or Barquey Burn. A small islet is indicated on the early OS maps, no longer shown when the loch level was lowered in the late 1890s or early 1900s. Roy's map of 1747 shows the then sizeable loch with a roughly circular island near the centre of the loch; the outflow joined the Water of Coyle near Coyle bridge. Armstrong's map of 1775 shows the loch.
The OS maps suggest that the water flow could be controlled so as to set the level of the loch. OS maps also show that the size has been greatly reduced and in 2011 only a small area of open water survives, surrounded by wetland with no significant outflow remaining. The main drain sets the present water level and the previous ditch is now infilled for part of its length with a pipe within it.
The height differential between the present outflow and the presumed natural overflow is illustrated by the 'fossilised' loch shore features. A quoted depth of 4.3 m or 14 ft for the early 19th century is reflected by this evidence. Although the old lochs outflow passes close to the site of the now demolished Bridgend Cottages, no evidence of a watermill survives.


The loch is eutrophic and is surrounded by a wide wetland margin that dries out progressively towards the surrounding pastures. Animals found at the site include willow warbler (Phylloscopus trochilus) are present, the European hare (Lepus europaeus), meadow brown, (Maniola jurtina), and small tortoiseshell (Aglais urticae).
Plants found include typical wetland species such as sedges, willows, and rushes. Hedge woundwort is plentiful, as are wild angelica (Angelica sylvestris) is plentiful, as are Hedge woundwort (Stachys sylvatica), yellow flag iris (Iris pseudacorus), and reed canary grass, (Phalaris arundinacea). The open water area exhibits yellow pond-lily (Nuphar lutea). Wild angelica, reedmace (bullrush), yellow meadow vetchling, Yorkshire fog grass, tussock grass, and meadowsweet were also noted and Brooklime speedwell grows within the ditch of the Joppa Burn inflow.


In the 19th century Lochend Loch was used for curling and probably ice skating. St. Quivox v Coylton is recorded for 20 January 1820 and again on 9 January 1862, both times playing for the Coylton medal. The presence of a small island is indicative of its use for breeding and hunting wildfowl and it is likely to have been used for fishing as fish were present.
The site in 2011 had waterfowl shooting hides and feeding areas for pheasants. Light grazing was noticeable up to the fence around the open water.


Blue Lake (Croatian: Modro jezero or Plavo jezero) is a karst lake located near Imotski in southern Croatia. Like the nearby Red Lake, it lies in a deep sinkhole possibly formed by the collapse of an enormous cave. The total depth from the upper rim is around 220 metres (720 ft), while water depth varies with season. In spring, when the snow from surrounding mountains melts, it can reach 90 m (300 ft), and in 1914 it reached 114 m (374 ft), overflowing the southern rim. The lake is a popular destination for hiking and sight-seeing.
Maximum dimensions of the lake are around 800 m × 500 m (2,600 ft × 1,600 ft), but they significantly vary due to big changes in the water level. At the end of the summer the lake may completely disappear.
In 1907 a road was built descending to the lake. In 1942, an earthquake caused a large rockfall, resulting in reduction of the lake's depth.


Lake Matheson (Māori: Te Ara Kairaumati) is a small glacial lake in South Westland, New Zealand, near the township of Fox Glacier. It was a traditional food-gathering place for local Māori. An easy walking track circles the lake, which is famous for its reflected views of Aoraki / Mount Cook and Mount Tasman.


Lake Matheson formed between two moraine terraces left by the rapid retreat of Fox Glacier / Te Moeka o Tuawe 14,000 years ago, at the end of the last glacial period. The retreating glacier left behind a valley and a huge slab of ice insulated by a deep layer of moraine gravel, which gradually melted and collapsed to form the lake bed. The lake is now about 12 kilometres (7.5 mi) from the current terminus of the glacier in the Southern Alps. Moraines, outwash gravels, and river gravels dammed the valley, and the lake grew, fed by small streams and seepage – there is no major river inflow or outflow.
Lake Matheson is 30 ha in area, with an approximately 1.5 km shoreline and an average depth of 12 m. The streams that feed it pass through dense native bush, and often accumulate foam after heavy rains. They carry organic matter and tannins from the forest, which colour the water a dark brown – this is the factor that limits visibility and enhances the mirroring effect from the lake. The lake water is acidic (the pH has been recorded as low as 5.5), low in nutrients, and sometimes almost de-oxygenated. These are all characteristics of a dystrophic brown-water lake that is accumulating organic matter; in the long run, the lake will gradually fill in and become a peat bog.


The lake and its small catchment are almost entirely surrounded by native podocarp forest. Around the edge of the lake the forest is mainly composed of Hall's tōtara (Podocarpus laetus), southern rātā (Metrosideros umbellata), kāmahi (Weinmannia racemosa), and rimu (Dacrydium cupressinum). Other forest trees include miro (Prumnopitys ferruginea), broadleaf (Griselinia littoralis), kahikatea (Dacrycarpus dacrydioides), mountain horopito (Pseudowintera colorata), and pate (Schefflera digitata). At the point where the walkway climbs higher tōtara becomes less common and rimu and Quintinia serrata more common. The lake contains the rare aquatic plant stout water milfoil (Myriophyllum robustum). Wetlands bordering the lake contain flax (Phormium tenax) and spike sedge (Eleocharis acuta).

Ferns and mosses are common around the lake, and notable species include the Prince of Wales feathers fern (Leptopteris superba), shining spleenwort (Asplenium oblongifolium) and hanging spleenwort (Asplenium flaccidum). The giant moss Dawsonia can be seen at several points.
Fernbirds or mātātā (Poodytes punctatus) can be found in the wetland around the lake, and the endangered species of Ōkārito brown kiwi known as rowi (Apteryx rowi) have been released in the neighbouring Omoeroa Ranges since December 2018. A local ecotourism operation began Project Early Bird in conjunction with the Department of Conservation in 2018 by setting 80 traps around Lake Matheson to catch introduced predatory mammals like stoats and rats.


Daubensee is a lake at Gemmi Pass in Valais, Switzerland. It is the site of the annual Shepherd Festival held on the last Sunday in July. It has a surface area of 69 ha (170 acres).


The Tiefwarensee is a lake on the northeastern perimeter of the town of Waren (Müritz) in the district of Mecklenburgische Seenplatte in the German state of Mecklenburg-Western Pomerania. The lake is separated from the Binnenmüritz to the southwest by a 300 metre wide isthmus. The lake is a glacial tunnel valley lake nestling in an ice-age formed meltwater channel, that runs into Lake Müritz from the north. It has one sizeable bay on its southern shore. It is roughly 2,600 metres long and 780 metres wide. Waren's town centre lies on the southern shore of the lake. The lake thus plays a central role as a recreation area for Waren. For example, there is a canoe and boat hire service on the lake and fishing is also allowed. The Tiefwarensee belongs to the Torgelower See nature reserve, and its northeastern shore is part of the Ostufer Tiefwaren – Falkenhäger Bruch Nature Reserve. Power boats and windsurfing are not permitted.
The ten-kilometre-long Tiefwarensee Ice Age Trail runs around the lake. It may be negotiated on foot or by bicycle..


Cueifong Lake (Chinese: 翠峰湖; pinyin: Cuìfēng Hú) is a lake in Taipingshan National Forest Recreation Area, Nan'ao Township, Yilan County, Taiwan.


The lake is the largest alpine lake in Taiwan, located at an altitude of 1,900 meters. The lake covers an area of 20 hectares. Its water is clear and unpolluted. During rainy season, the area of the lake can reach up to 25 hectares.


Hanging Lake is a lake in the U.S. State of Colorado. It is located in Glenwood Canyon, about 7 miles (11 km) east of Glenwood Springs, Colorado and is a popular tourist destination. When open, the lake is reached via a trailhead located along the Glenwood Canyon Bike and Pedestrian Path that runs along the north side of I-70 in the bottom of the canyon. The trail follows Dead Horse Creek, a tributary of the Colorado River and ascends some 1,000 feet (300 m) in elevation for 1.2 miles (1.9 km) from the trailhead to the lake.


The travertine lake is extremely sensitive, therefore dogs, drones, fishing, and swimming (or bodily contact with water at Hanging Lake) are strictly prohibited. Do not harass, feed, or disturb wild animals, particularly during winter when they are conserving energy to stay alive. During winter, visitors are strongly warned to stay off the frozen lake (whether partially or fully frozen) because it is extremely dangerous to walk on the ice. Even during winter, walking off-trail is not permitted. Parking at Hanging Lake parking area is only allowed Nov. 1 - April 30 with a reservation. Parking is not allowed along entrance or exit ramps of I-70 at any time.


Jordan Pond is an oligotrophic tarn in Acadia National Park near the town of Bar Harbor, Maine. The pond covers 187 acres (76 ha) to a maximum depth of 150 feet (46 m) with a shoreline of 3.6 miles (5.8 km).
The pond was formed by the Wisconsin Ice Sheet during the last glacial period. Penobscot Mountain (1194 ft) rises to the west, while Pemetic Mountain (1247 ft) rises to the east. Two roche moutonnées known as The Bubbles (North and South) rise above the northeastern shoreline. The southern end is constrained by glacial debris and an artificial dam.
The pond has clear water, with visibility normally 44 feet (13.4 m) and occasionally recorded up to 61 feet (18.6 m), the deepest recordings in Maine. The pond exhibits high levels of dissolved oxygen, and low levels of plant nutrients and plant life.
Some types of boating are permitted, but people and pets are prohibited from entering the water as it is the water supply for the village of Seal Harbor.


Jordan Pond was previously thought to be the only pond containing the type specimen of a quillwort species described by Alvah Augustus Eaton. The species was formerly known as Isoetes macróspora var. heteróspora (or Isoetes heterospora) but is now considered to be a synonym for Isoetes lacustris, which is found in both North America and Europe.  Four other quillwort species are also found in the lake, along with three species of pondweed, two species each of rushes, bur-reeds, and carnivorous bladderworts, and at least six other species of plants.
Fish species in the lake include landlocked Atlantic salmon, lake trout, brook trout, rainbow smelt, four species of minnow, banded killifish, three-spined stickleback, pumpkinseed sunfish, and the American eel.  The landlocked salmon, lake trout, smelt, sticklebacks, and at least one species of minnow are known to have been introduced or stocked by humans.


Lochend Loch, which once had nearly three acres in surface area is now only a small freshwater loch remnant. It lies in the South Ayrshire Council Area, lying on the hill above Joppa, between Gallowhill and Lochend Farm.


Trekanten (English: The Triangle) is a small lake in southern-central Stockholm, Sweden.
Trekanten is located in a park furnished with an artificial bathing beach and various planted-out fish species.  It has a small drainage area with no major feeders.  In the early 1980s, potable water was poured into the lake while water from the bottom of the lake was pumped out.  These operations resulted in a significant reduction in levels of phosphorus but failed to affect levels of nutrients and oxygen depletion in the bottom layers.  Levels of lead and copper are among the highest documented in any lake in Stockholm.  Whilst the lake flora and fauna is roughly representative for Stockholm, the lake forms a natural link between the bays Årstaviken and Vinterviken.


In late summer, phytoplankton stock is dominated by green algae paired equal levels of diatoms, cyanobacteria, and a species of eutroph carapace flagellate (Ceratium hirundinella).  Several of the blue green algae present in the lake are potentially poisonous and, notwithstanding non-alarming levels, therefore carefully monitored near the bathe.  Lacking soft and shallow bottom areas near the shore, the lake contains only commonplace vegetation, save for the population of crack willow and the hybrid between white willow and bay willow found on the southern shore.  Aquatic plants are dominated by white waterlily, amphibious bistort, and occasional curled pondweed (uncommon to Stockholm).
An inventory of lake bed fauna in 1997 produced a list of only 29 species/taxa including most common species, mostly freshwater gastropods, fireflies, and leeches but no beetles.  A rotenone treatment in 1986 didn't affect the populations of crucian carp and signal crayfish still dominating the fauna.  Perch was introduced shortly after the treatment, and northern pike and roach is believed to have found their way into the lake by themselves.  Crucian carps are decimated by trawling annually and the population of roach has increased considerably since 2001.  Carp, rainbow trout, and signal crayfish have been planted-out.
In early summer the lake is home to a number of birds including thrush nightingale, common chaffinch, garden warbler, and blackcap.  Other birds common to Stockholm, such as mallard, Eurasian coot, tufted duck, and great crested grebe, are found by the lake, while heron visit the lake and common merganser fish here during winters.  No amphibians have been documented by the lake.


WikiWeb_Avalanche Lake (Ooty, Tamil Nadu, India)_2

Avalanche Lake is an important tourism destination in the Nilgiris district. The lake is surrounded by a rolling landscape with blooming flowers like magnolias, orchids and rhododendrons. Tourists can traverse beside the lake through winding paths around the lake. Tourists visiting the lake can also engage themselves in Trout fishing. A trout hatchery is established near the lake, from where visitors can get fishing rods and other fishing accessories required for trout fishing. The lake is also used by tourists as a camp site wherein they pitch tents near the lake. Other tourist activities in the area include rafting across the lake and trekking the nearby hilly regions like Upper Bhavani where there are thick forests and untouched wild habitats.


Deoria Tal (also Devaria or Deoriya) is a lake about 3 km (1.9 mi) from the villages of Mastura and Sari on the Ukhimath-Chopta road in the state of Uttarakhand in India. Situated at an altitude of 2,438 metres (7,999 ft) in the Garhwal Himalayas, it has heavily wooded, lush green surroundings with snow-covered mountains (Chaukhamba being one of them) in the backdrop. It is considered sacred by Hindus. And deoria tal camping rooms available

Please booking and visit


Jeeps are available from Ukhimath to reach Sari, a nearby village, via Mastura village. For return journey, one can go down trekking to Mastura to get a shared jeep.
Alternately, one can trek 7 km (4.3 mi) to Deoria Tal from Ukhimath. Even though, trekkers are no longer allowed to camp at the famous Deoriatal , there are options of jungle trekking, videography, etc. There are a couple of shops that sell tea and snacks, but these close at sundown. Trekkers usually combine this trek with the nearby trek to Tungnath (the highest Hindu shrine devoted to Lord Shiva) and Chandrashila, which are approached from Chopta.


Semsvannet is a lake in Asker municipality in Viken county, southwest of Oslo, in Norway. The lake is situated close to, for the Norwegians, famous places such as the ridge Skaugumsåsen, the old cultural house Tangen and Skaugum the official residence of the heir to the throne of Norway, i.e. the crown prince or princess of Norway. The status of Semsvannet as a nature reserve was upgraded when the area was protected as a conservation area October 2, 1992. The lake and its vicinity was elected a millennium site in the year 2000.


Lake Semsvannet is 0.75 km² (190 acres) and is situated at a height of 145 meters (476 feet) above sea level. The greatest depth is 34 metres (112 ft). To the lake flows the river Gupelva. From the lake flows the river Askerelva. Regarding the inhabitants of the lake, fish, there are: Northern pike (Esox lucius), European perch (Perca fluviatilis) and Roach (Rutilus rutilus). There are also smaller populations of Brown trout (Salmo trutta), Arctic char (Salvelinus aplinus) and European whitefish (Coregonus lavaretus).


For generations, Semsvannet has been utilized as a lake for swimming, especially among the, at the time, permanent residents at Tangen, et cetera. It is possible to perform cross-country running around the lake or – according to the Norwegian expression – "gå på tur" [eng. do a walkabout, to trek]. The distance is then 4.8 km (3.0 mi). For outdoor and athletic people there are summer trails and winter ski trails, into the Vestmarka, that begins here.


Glaslyn (Welsh: Blue lake) is a lake in the Snowdonia National Park in Gwynedd, north-west Wales.
It is found at approximately 600 metres (2,000 ft) above sea level in a cwm on the eastern flanks of Snowdon. It is a rough ellipse in shape, about 500 metres (1,600 ft) east–west and about 300 metres (1,000 ft) north–south, and the Miners' Track runs along the northern shore.
It has a maximum depth of 39 m (127 feet), and contains about 59 million cubic feet (1.7 million cubic metres) of water.
Glaslyn is the source of the Afon Glaslyn, the major river of Gwynedd, which runs east to the reservoir of  Llyn Llydaw before turning south-west to reach the sea at Porthmadog.
In 2020, small particles of microplastic pollution – deposited by rain – were found in the lake, triggering a further investigation of the extent of environmental damage in UK lakes and mountains.


Vinstre is a lake in the municipality of Vang and Øystre Slidre in Innlandet county, Norway. It has an area of 28.26 km² (10.91 sq mi). It is at an elevation of 1,032 m above sea level. Along its northern shore runs the Jotunheimvegen summer toll road, built in the 1950s as a result of hydroelectricity development affecting the operation of the earlier milk boat service.


The name of the lake is (maybe) derived from the verb vinda 'bend, twist, wind', adding the suffix -str. The name is then referring to the twisted shape of the lake. The river Vinstra starts from the lake.


Loch Monar is a freshwater loch situated at the head of Glen Strathfarrar, in the West Highlands of Scotland. Since the 1960s, it has been dammed as part of the Affric-Beauly hydro-electric power scheme.
The loch is fed by a number of small burns running off the surrounding hills. The loch's primary outflow is the Garbh-uisge, which joins with the Uisge Misgeach to form the River Farrar.
Much of the area around Loch Monar is remote and mountainous. This include the Munros of Sgùrr a' Chaorachain, Sgùrr Choinnich, Maoile Lunndaidh, Lurg Mhòr and Bidein a' Choire Sheasgaich.


Lake Thetis is a saline coastal lake in the Mid West region of Western Australia. The lake is situated east of the small town Cervantes, 2 kilometres (1.2 mi) inland from the Indian Ocean, on a Quaternary limestone pavement.


The lake is one of only a few places in the world with living marine stromatolites. The Lake Thetis stromatolites exhibit unusual columnar branching. These narrow, closely spaced and almost parallel columns are extremely rare in modern stromatolites.
Alongside the stromatolites, a diverse array of benthic microbial communities, such as algal mats, inhabit various layers of the lake. Some of these algal mats are associated with the stromatolites while most confine themselves to a particular area such as the high foreshore areas, splash zone or the central basin of the lake.
The lake water is alkaline and nutrient poor but provides an ideal environment for bottom dwelling microbial communities. The lake contains some small fish, amphipods and a few crustacean species adapted to living in highly saline environments.
The stromatolite community is threatened by nutrient enrichment and physical crushing. An interim recovery plan is currently being written which will provide direction to further protect this extremely valuable community for future generations.


Rydal Water is a small body of water in the central part of the English Lake District, in the county of Cumbria. It is located near the hamlet of Rydal, between Grasmere and Ambleside in the Rothay Valley.
The lake is 1,290 yards (1.18 km) long and varies in width up to a maximum of 380 yards (350m), covering an area of 0.12 mi² (0.31 km²). It has a maximum depth of 55 ft (17m) and an elevation above sea level of 177 ft (54m). The lake is both supplied and drained by the river Rothay, which flows from Grasmere upstream and towards Windermere downstream.
The waters of the southern half of the lake are leased by the Lowther Estate to the National Trust, whilst those of the northern half belong to the estate of Rydal Hall. Navigation is prohibited, except for residents of Rydal Hall.
Numerous walks are possible in the surrounding hills, as well as a walk around the lake itself, which takes in Dove Cottage and Rydal Mount, both homes to William Wordsworth, and Rydal Cave, a former quarry working. At the western end of the lake, steps lead to Wordsworth's Seat, which is considered to have been Wordsworth's favourite viewpoint in the Lake District.
White Moss House, at the northern end of the lake, is believed to be the only house that Wordsworth ever bought. He bought it for his son Willie, and the family lived there until the 1930s. Nab Cottage overlooks the lake and it was once home to Thomas de Quincey and Hartley Coleridge, the son of Samuel Taylor Coleridge. Close by is the historic Rydal Hall.


Crestasee (Romansh: Lag la Cresta) is a small lake shared by the municipalities of Flims and Trin in the Grisons, Switzerland. From 1892 a guest house on its northern end served as pension and still is a restaurant today in its original state.
There is no tributary to the lake. The rough character of the whole area derives from being a debris area of the gigantic Flims Rockslide, where waters flow underground until feeding lakes at certain spots such as Crestasee, Caumasee or Lag Prau Pulté.
Less than 100 yards (91 m) from its northern end a gorge called "Felsbachschlucht" is formed by river Flem, coming from Flims, whose Romansh name is also Flem. The waters from the lake and river are independent, and of course the river had only some 10 000 years to create the gorge as this is the age of the rockslide.
The water from the lake forms a small stream and enters the Flem river after a very short run, not called a special name for its short length.
In summer it is well known for swimming and offers facilities (such as a kiosk, toilets, changing room, boats and SUP's to rent) to enjoy this. An entrance charge will be collected by an employee of the restaurant, walking around the lake once or twice a day. Crestasee can be reached from Flims via the Felsbachschlucht gorge or wide forest paths, as well as from Trin Mulin or the public post car stop Felsbach/Crestasee on the main road, to where it is connected by a nice and short path. Motorists have to walk a similar distance to the lake, as there is no access to the lake by car and signposted parking is well off the lake.
A forest walk leads to Conn, to see the Ruinaulta gorge formed by the Rhine, still within the same huge rockslide debris area, or to the Lag la Cauma.


Lough Inagh (Irish: Loch Eidhneach, meaning 'lake of the place of ivy') is a freshwater lake in the Inagh Valley, in Connemara, Galway, in the west of Ireland.


Lough Inagh is located about 23 km (14 mi) east of Clifden on the R344 road in the Inagh Valley. The Twelve Bens range lies to the west of the lake, with Derryclare 677 metres (2,221 ft) and Bencorr 711 metres (2,333 ft) directly overlooking the lake.  The bulk of the Maumturks range and its long central spine lies to the east of the lake, with two highest peaks of Letterbreckaun 677 metres (2,221 ft) and Binn idir an Dá Log 702 metres (2,303 ft), also overlooking the Lough.
Lough Inagh is fed from several mountain streams in the area, but most importantly from the Gleninagh River that starts high up in the Gleninagh Valley on the slopes of Benbaun and Bencollaghduff, and the Tooreennacoona River. After flowing into Lough Inagh, the river flows into Derryclare Lough, and then into Ballynahinch Lake, where it eventually joins the Owenmore River where is flows into Bertraghboy Bay.


Lough Inagh is noted for its lake and river fishing with spring salmon, grilse and sea trout (depending on season), and the fishing is mostly done from boats, however, the lake is too big for rowing and an outboard motor is recommended (there are a couple of submerged rocks so caution should be taken).
The Lough and its fishing rights are privately owned and controlled by local fishing lodges in the Inagh Valley.  Irish fishing author, Peter O'Reilly, said about Lough Inagh that "This lough will take more than one day to explore adequately, for it can be one of the best".


Yueyaquan (Chinese: 月牙泉; pinyin: Yuèyá Quán) is a crescent-shaped lake in an oasis, 6 km south of the city of Dunhuang in Gansu Province, China.


Lake Pátzcuaro (Spanish: Lago de Pátzcuaro) is a lake in the municipality of Pátzcuaro, Michoacán, Mexico.
Lake Pátzcuaro lies in an endorheic basin, which does not drain to the sea. A watershed area of 929 square kilometres drains into the lake, of which 126.4 are the water body. The Lake Pátzcuaro watershed extends 50 kilometres east–west and 33 kilometres from north to south. Lake Pátzcuaro lies at an elevation of 1,920 metres, and is the center of the basin and is surrounded by volcanic mountains with very steep slopes. It has an average depth of 5 metres and a maximum of 11. Its volume is approximately 580 million cubic metres.
The Lake Pátzcuaro basin is of volcanic origin. At times it has been part of an open and continuous hydrological system formed by Lake Cuitzeo, Pátzcuaro and Lake Zirahuén, which drained into the Lerma River. Today, like lakes Cuitzeo and Zirahuén, it is a closed basin, although ecologists consider it a sub-basin of the Lerma-Chapala basin.


The lake is surrounded by extensive wetlands, which have been designated as a Ramsar site since 2005. Cattails and other reedy vegetation are the dominant wetland vegetation, in dense stands over 2 meters tall. Typical wetland plant genera include Typha, Scirpus, Eleocharis, and Cyperus. The dominant species of aquatic vegetation are Potamogeton illinoensis, Scirpus pectinatus, Typha latifolia, T. domingensis, and Nymphaea mexicana.
The wetlands are extremely important for birds, both year-round inhabitants and migrating waterfowl. Close to 200 species inhabit the wetlands, including some endemic species such as the black-polled yellowthroat (Geothlypis speciosa). Two native species have not been observed recently;  the yellow rail (Coturnicops noveboracensis) has not been seen since 1964 and may be locally extinct, and the endemic slender-billed grackle (Quiscalus palustris) is presumed extinct.
The Lake Pátzcuaro salamander (Ambystoma dumerilii) is endemic to the basin. Among other aquatic or semi-aquatic animals, several are largely or entirely restricted to the Lake Pátzcuaro system, such as the rough-footed mud turtle of the subspecies tarascense, the essentially harmless Mexican garter snake of the subspecies  patzcuaroensis, the fish Pátzcuaro chub (Algansea lacustris) and Pátzcuaro allotoca (Allotoca diazi), and the dwarf crayfish Cambarellus patzcuarensis.
The lake and its surrounding wetlands have undergone significant environmental changes over the past 50 years. logging and agriculture in the surrounding watershed have contributed to siltation of the lake (1 cm / year - 1.2 million cubic meters / year), and water diversion for agriculture and urbanization has reduced the size of the lake by 40 square kilometers, and 2.6 meters in depth. Other threats include untreated sewage, the introduction of exotic species, and chemical pollution.
In February 2021, members of the Supreme Indigenous Council of Michoacán (CSIM) noted that political opportunism, corruption, and a lack of coordination have undermined efforts to clean up the lake. They noted that since 2006 MXN $5 billion has been spent, and since 1934, 2,300 studies have been conducted, yet 79% of the inhabitants of Pátzcuaro, Erongarícuaro, Quiroga, and Tzintzuntzan live in poverty and 40% in extreme poverty.


Herthasee is a lake on the island Rügen, Mecklenburg-Vorpommern, Germany. At a length of 170 m and a width of 140 m, it covers a surface area of 0.202 km². It has a maximum depth of 11 m. It is located in the center of the Jasmund National Park and its famous chalk cliffs.
At its embankment, the lake features a Slavic hill fort called Herthaburg, with a height of 17 m. It was constructed and inhabited between the 8th and 12th century.


Upvan (or Upavan) Lake is located in Thane in the Indian state of Maharashtra. It is known for hosting the Sanskruti Arts Festival. Here one can also view thousands of Ganpati idols which are brought here for immersion on final day of Ganeshotsav. It was founded and reconstructed by J.K. Singhania for water supply. Singhania also constructed the lord Ganesha's temple at Upvan lake. The lake is located near Gawand Baug, Shivai Nagar, Ganesh Nagar, Vasant Vihar and Vartak nagar. This is one of the recreational areas for people who live in Thane. It is one of the biggest lakes in Thane, surrounded by Yeoor Hills, and lies in the Pokhran-II area. One of the eco friendly lake of city, Upvan Lake is regarded as Thane's ‘lover's paradise’. Upvan lake forms a junction of the Pokhran I and Pokhran II roads. Once, the major source of water for the entire Thane city, Upvan lake is now used primarily for recreation. The official residence of the Mayor of Thane Municipal Corporation lies adjacent to the lake.
Upvan was decorated during Sanskruti Arts Festival 2015. Over 50,000 people visit the lake during the festival.


Llyn Gwynant is a lake in Snowdonia, Wales.
Llyn Gwynant lies on the River Glaslyn, in the Nant Gwynant valley, and is about 1¼ miles (2 km) north east of Llyn Dinas; the village of Bethania lies between them.
Snowdon lies 2 miles (3 km) to the north west.  The lake is natural, having been formed by glacial action and is 120 acres (50 hectares) in size. It is a popular place for canoeing and kayaking with easy access from the A498 road which runs along its south bank.
It was used as a filming location in the 2003 film 'Lara Croft Tomb Raider: The Cradle of Life'.
The view towards Llyn Gwynant and Moel Hebog is one of the most photographed in Snowdonia.


Etang de la Gruère is a small lake in the Jura range near Saignelégier, Canton of Jura, Switzerland. The lake and the surrounding bog is a nature preserve. The lake was formed in the 17th century, when a dam was built for a mill.


Lough Finn (Irish: Loch Finne) is a freshwater lough (lake) in County Donegal, Ireland. The lough, along with its neighbouring village of Fintown, was named after a mythological woman, Finngeal, who drowned in the lake after attempting to save her wounded brother Feargamhain. The water from Lough Finn outflows into the River Finn.


Loch Loyne is a loch in the Northwest Highlands of Scotland. Loch Loyne lies between Glen Garry and Glen Cluanie. The A87 road runs beside the eastern side of the loch.


Lake Tarleton is a 334-acre (1.35 km²) water body located in Grafton County on the western edge of the White Mountains in New Hampshire, United States. The lake is located in the towns of Piermont and Warren. Water from Lake Tarleton flows via Eastman Brook west to the Connecticut River.
Kingswood Camp for Boys is located on the lake. The Appalachian Trail runs nearby on Mount Mist, then continues north to Mount Moosilauke, with both mountains overlooking the lake.
The lake is classified as a cold- and warmwater fishery, with observed species including rainbow trout, brown trout, lake trout, smallmouth bass, chain pickerel, and horned pout.
Lake Tarleton State Park offers an unguarded swimming beach and opportunities for swimming, canoeing and fishing.


Tal-y-llyn Lake, (Welsh: Llyn Mwyngil), also known as Talyllyn Lake and Llyn Myngul, is a large glacial ribbon lake in Gwynedd, North Wales. It is formed by a post-glacial massive landslip damming up the lake within the glaciated valley. The hamlet of Talyllyn lies at the west end of the lake.


Tal-y-llyn Lake is situated to the north of Machynlleth, at the foot of Cadair Idris, in the Snowdonia mountain range of Gwynedd, Wales. The River Dysynni flows from the lake, through the village of Abergynolwyn, and discharges into the sea north of Tywyn.
There is a route leading to the summit of Cadair Idris from near the lake and the narrow gauge Talyllyn Railway has its eastern terminus at nearby Nant Gwernol near the village of Abergynolwyn, within the parish of Tal-y-llyn, the hamlet at the southern end of the lake.


Loch Enoch is a multi-basin freshwater loch in Galloway, to the east of Merrick and south of Mullwharchar. The loch is situated in a granite basin and has several small islands and some beaches on its shore. The sharp granite sand of these beaches was collected and sold for sharpening knives and scythes. The catchment area's vegetation is mainly Purple Moor Grass and Heather.
The loch's outflow supplies Loch Doon and the River Doon, both in Ayrshire.


Lonar Lake, also known as Lonar crater, is a notified National Geo-heritage Monument, saline, soda lake, located at Lonar in Buldhana district, Maharashtra, India. Lonar Lake is an astrobleme created by a meteorite impact during the Pleistocene Epoch. It is one of only four known hyper-velocity impact craters in basaltic rock anywhere on Earth. The other three basaltic impact structures are in southern Brazil. Lonar Lake has a mean diameter of 1.2 kilometres (3,900 ft) and is about 137 metres (449 ft) below the crater rim. The meteor crater rim is about 1.8 kilometres (5,900 ft) in diameter.
Lonar Crater sits inside the Deccan Plateau – a massive plain of volcanic basalt rock created by eruptions some 65 million years ago. Its location in this basalt field suggested to some geologists that it was a volcanic crater. Today, however, Lonar Crater is understood to be the result of a meteorite impact. The water in the lake is both saline and alkaline.
Geologists, ecologists, archaeologists, naturalists and astronomers have published studies on various aspects of the ecosystem of this crater lake.
Although the crater's age was previously estimated to be 52,000 ± 6,000 years, newer studies suggest an age of 576,000 ± 47,000 years.
The Smithsonian Institution, the United States Geological Survey, Geological Survey of India, the University of Sagar and the Physical Research Laboratory have conducted extensive studies of the site. Biological nitrogen fixation was discovered in this lake in 2007.
A 2019 study, conducted by IIT Bombay found that the minerals in the lake soil are very similar to the minerals found in moon rocks brought back during the Apollo Program. The lake was declared a protected Ramsar site in November 2020.


A series of small hills surround the basin, which has an oval shape, almost round, with a circumference at top of about 8 km (five miles). The sides of the basin rise abruptly at an angle of about 75°. At the base of the sides, the lake has a circumference of about 4.8 km (three miles). The slopes are covered with tree-savannah, housing teak (Tectona grandis), Wrightia tinctoria, Butea monosperma, and Helicteres isora, and with shrub-savannah housing Acacia nilotica and Ziziphus spp.. Along the lake shore, non-native Prosopis juliflora is spreading. Millet, maize, okra, banana, and papaya are the main cultivated crops.
The water of the lake contains various salts and sodas. During dry weather, when evaporation reduces the water level, large quantities of soda are collected. Two small streams, named Purna and Penganga, drain into the lake, and a well of fresh water is located on the southern side, close to the water's edge.


The chemical characteristics of the lake shows two distinct regions that do not mix – an outer neutral (pH 7) and an inner alkaline (pH 11) each with its own flora and fauna.The lake is a haven for a wide range of plant and animal life.
The site has 160 bird, 46 reptile and 12 mammal species. Resident and migratory birds such as black-winged stilts, brahminy ducks, grebes, shelducks (European migrants), shovellers, teals, herons, red-wattled lapwings, rollers or blue jays, baya weavers, parakeets, hoopoes, larks, tailorbirds, magpies, robins and swallows are found on the lake.
Among reptiles, the monitor lizard is reported to be prominent. The lake is also home to thousands of peafowls, chinkara and gazelles. The area of 3.83 km² (1.48 sq mi) was declared as Lonar Wildlife Sanctuary by the government on 20 November 2015.


Jenny Lake is located in Grand Teton National Park in the U.S. state of Wyoming. The lake was formed approximately 12,000 years ago by glaciers pushing rock debris which carved Cascade Canyon during the last glacial maximum, forming a terminal moraine which now impounds the lake. The lake is estimated to be 256 feet (78 m) deep and encompasses 1,191 acres (482 ha). Jenny Lake is considered to be a major focal point in Grand Teton National Park, with many hiking trails, scenic boat rides, and quick access to the major climbing routes onto the tallest peaks of the Teton Range.
Jenny and Jackson Lakes are the only lakes in Grand Teton National Park where motorboats are permitted; both lakes have scenic tours available. A 2005 study of the water quality of the lakes in Grand Teton National Park indicated that all the lakes in the park were still considered pristine and that they had not been impacted by air or water pollution.
Jenny Lake is a starting point for many day and overnight hiking trips. The 7.1-mile (11.4 km) Jenny Lake Trail loops around the lake and is considered to be relatively easy due to the small altitude gain of 700 feet (210 m). However, the altitude increases rapidly once Cascade Canyon is entered.
Jenny Lake is named after a Shoshone Indian woman who married an Englishman, Richard "Beaver Dick" Leigh. Jenny, and their 6 children, died of Smallpox in 1876.


Oppstrynsvatn (also known as Oppstrynsvatnet, Strynevatnet, or Strynevatn) is a lake in the municipality of Stryn in Vestland county, Norway.  It is located about 8 kilometres (5.0 mi) east of the village of Stryn (the administrative centre of the municipality).  The villages of Flo, Oppstryn, and Erdal are located on the shores of the lake.
The lake has an area of 22.87 square kilometres (8.83 sq mi) and is surrounded by many large mountains and glaciers which feed into the lake.  The main outflow of the lake is the river Stryneelva which flows west into the Nordfjorden.
Some of the local attractions include the Jostedalsbreen nasjonalparksenter, Jostedalsbreen National Park, the mountain Skåla, and the glacier Tindefjellbreen.  The Norwegian National Road 15 highway runs along the southern shore of the lake.  Oppstryn Church sits right on the shore overlooking the lake.


Obersee ("upper lake") or Oberer Arosasee is the lake in the center of Arosa, a resort in the Grisons, Switzerland. The lake has a surface area of 7.1 ha (18 acres) at an elevation of 1734 m. Arosa's lower lake (Untersee) is at 1691 m.


Lake Mogan (Turkish: Mogan Gölü, also called Gölbaşı Gölü) is a small lake in Ankara Province, Turkey.


The lake is 25 kilometres (16 mi) south of the Ankara city center within the intracity district of Gölbaşı at about 39°46′N 32°48′E.  The eastern shore lies along the highway  D.750  which traverses Turkey from north to south. The altitude of the water surface with respect to sea level is about 972 metres (3,189 ft) and the surface area of the lake is about 5.61 square kilometres (2.17 sq mi). It has a circumferential length of 14 kilometers with a length of 11 km. and an average width of 500 meters. The average depth of the lake (in wet season) is about 5 meters.


Lake Mogan has always been one of the picnic areas of Ankara. Along the shore there are many restaurants as well as camping and fishing points where the main  game fish is carb fish. In 2001 the Metropolitan municipality of Ankara has established a recreation area named Mogan Park at the west shore of the lake. The total area of the park is 601,879 square metres (6,478,570 sq ft) where 203,650 square metres (2,192,100 sq ft) is reserved for the endangered waterfowl. The total length of the walking track in the area is 130 kilometres (81 mi)


Seeli (literally "small lake") or Seelisbergsee is the lake on Seelisberg in Uri, Switzerland, that gives the place its name. Its surface area is 18 ha (44 acres).


Martham Broad is a  60-hectare (150-acre) national nature reserve north of Great Yarmouth in Norfolk. It is managed by the Norfolk Wildlife Trust, and is part of the Upper Thurne Broads and Marshes Site of Special Scientific Interest. It is also part of the Broadland Ramsar site and Special Protection Area, and The Broads Special Area of Conservation.
This reserve is composed of two shallow broads divided by the River Thurne, together with fen, reedbeds and marshes. There are a number of bat species and breeding birds include bearded tits, common terns, Cetti's warblers and marsh harriers.
There is public access to the site.


The lac Jacques-Cartier, main source of the Jacques-Cartier River, is a glacial lake located in the Laurentides Wildlife Reserve, about 90 km to the north of the city of Quebec, in the unorganized territory of Lac-Jacques-Cartier, in the La Côte-de-Beaupré Regional County Municipality, in the administrative region of Capitale-Nationale, in the province of Quebec, in Canada.
The area around the lake is served by the route 175 which passes on the west shore, for the needs of forestry and recreational tourism activities.
Forestry is the main economic activity in this sector; recreational tourism, second.
The surface of Lake Jacques-Cartier is usually frozen from the beginning of December to the end of March, however the safe circulation on the ice is generally made from mid-December to mid-March.


The main hydrographic slopes near Lac Jacques-Cartier are:
north side: Pikauba River, Lac des Pas Perdus, Verchères Lake, Jacqueline Lake, Franchère Lake;
east side: Montmorency River, Malbaie River, Malbaie Lake, Neiges Lake, rivière du Gouffre, rivière à la Loutre ;
south side: Montmorency River, Sept-Îles Lake, Jacques-Cartier River, Jacques-Cartier North-West River, Sautauriski River;
west side: Beauséjour lake, Launières River, Banville lake.
The lake is located in the unorganized territory of Lac-Jacques-Cartier. The Nadreau Lake constitutes the head water body of the Jacques-Cartier River. This lake receives the waters on the west side of two small lakes: Plamondon lake (altitude: 844 metres (2,769 ft)) and an unnamed lake (862 metres (2,828 ft)). Lake Nadreau discharges 180 m north into Lake Grandpré (altitude: 847 m). The latter empties westwards into "Petit Pré lake" (440 m long; altitude: 838 m).
From the mouth of "Lac Petit Pré", the Jacques-Cartier River flows 15.6 km northwest in the county of Montmorency to reach Lake Jacques-Cartier.
Lake Jacques-Cartier, 9.2 km long, 1.8 km wide on average and 69 m deep, is the largest lake in the Laurentides Wildlife Reserve. At an altitude of approximately 795 m, it borders, to the east, Mont Camille-Pouliot (1,006 metres or 3,301 feet). At its southern end is a hydroelectric dam, built in 1922.
Between the lake and the mountain, pass boulevard Talbot(or route 175), same as a highway rest area called L'Étape.


In this lake, you can fish for gray trout (lake trout).
There is also the "Petit lac Jacques-Cartier" (47.405785°N 71.529751°W). This is why we have long talked about the Great Jacques-Cartier Lake to distinguish it from the Small.


Lake Tritriva is a volcanic lake in southwest-central Madagascar, in the region of Vàkinankàratra, located near the village of Belazao. In a distance of 15 km from Antsirabe, it is easy to reach by the National Road 34.
There's a strict Fady (taboo) for this lake and swimming is not allowed.
The lake fills an extinct crater in a region notable also for the presence of many hot springs. It sits in the vent of an oval volcanic cone enclosed in vertical gneiss cliffs. The rim of the cone is about 2,000 m (6,600 ft) above sea level, while the surface of the lake is approximately 50 m (160 ft) below the rim. The lake's water level drops during the rainy season and rises when the monsoon rains have ceased.


Tixall Wide, also known as Tixall Broad or The Broad Water, is a body of water that forms part of the Staffordshire and Worcestershire Canal near Tixall in Staffordshire, England, to the south of the former Tixall Hall.
The lake was probably created during the construction of the canal in 1771.
At that time, the hall was owned by Thomas Clifford, the fourth son of Hugh Clifford, 3rd Baron Clifford of Chudleigh, and the grounds had been designed on the advice of the landscape architect Lancelot "Capability" Brown.
It is said Clifford "gave permission for the canal to pass through his land on the condition that it was made ... wide enough to look like a lake from the house". and thus in order not to spoil the view.
The towpath is a very popular overnight mooring spot. Boaters moored here, or just passing through, have an excellent view of the magnificent Elizabethan gatehouse that is the only remaining part of Tixall Hall.
It has also been suggested that the canal was routed to utilise a lake that already existed, in which the angler and writer Izaak Walton had learned to fish.


Lake Lubāns is the largest lake in Latvia (in Latvian: Lubāns, Lubānas ezers or Lubāna ezers).
The lake lies in the center of the Eastern Latvian Lowland. It is a shallow drainage lake, fed by the Rēzekne, Malta, Malmuta and Lisinja rivers and several smaller brooks, with an outflow via the Aiviekste River into the Daugava River.
After damaging spring floods in 1926, several dams and ditches were constructed. The elevation of the lake is allowed to fluctuate between approximately 90 and 93 metres above sea level. At an elevation of 90.75 m the lake has an area of 25 km², increasing to about 100 km² at 92.75 m. In that state it is considered to be the biggest lake in Latvia.
Other small former lakes within the Lubanas basin have been artificially drained and the land is used for agriculture.


Verney Lake (French: Lac du Verney) is a lake at Aosta Valley, Italy. At an elevation of 2088 m, its surface area is 0.203 km².


The Seebensee is a natural high mountain lake (an ice-age affected, rock basin lake) at a height of 1,657 metres, south of Ehrwald in the Mieming Range. It is surrounded by the Vorderer Tajakopf in the east,  the Vorderer Drachenkopf in the south and the Ehrwalder Sonnenspitze in the west.
The Seebensee has no significant above-ground inflows and one outflow via the Seebenbach Falls and the Geißbach into the Loisach river. The lake may be reached from Ehrwald on a forest track via the Ehrwalder Alm, via the Seeben Klettersteig, a difficult  klettersteig, or via one of the two protected mountain trails Hoher Gang or Immensteig. From Biberwier, the lake may be reached via the arête of the Biberwierer Scharte, and from Leutasch through the Gaistal valley.
Near the lake (to the northeast) lies the managed alpine pasture of Seebenalm. To the south on a rock terrace above the lake is the Coburger Hut owned by the German Alpine Club.
The surface of the lake covers around 6.5 hectares, but it used to be larger. As a result of soil and vegetation analyses it has been deduced that there was a large area southeast of the lake which used to be part of it (today easily visible, especially from above, as a mainly grassy plain) but which has now silted up.


Baltieji Lakajai ( meaning White Lakajai ) is a major lake of eastern Lithuania, located about 12 miles east of Moletai, in Labanoras Regional Park of Utena County. It is part of the  Neris River basin, an elongated lake in a west–east direction. The lake is of glacial original as are all 9,000 and odd natural lakes (at the last official count and over 4,000 larger than half a hectare) covering 1.5% of the land area of Lithuania.
The Baltieji Lakajai is part of Labanoras Regional Park that was established in 1992.


Its total area is 6.998 km², its length is 8.6 km and its maximum width is 1.3 km. The lake has three islands which cover an area of 3.8 hectares. Along the waterhole is a 40–50 m deep ravine. The coastline of the lake has a total length of 24.5 km, and has many coves, bays and peninsulas. It is a relatively shallow lake with a maximum depth of 45 metres, narrow, and almost no beaches. Pine forests line the shores in most parts. The smaller Tramys lakes are just to the northeast, to the west is Lake Siesartis, and to the south (from west to east) is Lake Urkis, Lake Kertuojai and Juodieji Lakajai. The lake can be accessed by foot via Highway 114 from the north and Highway 173 from the southwest and is quite popular with vacationers.


Villages around the lake include Rudesa, Kamužė, Grūsis, Ažuraisčiai, Antalakaja, Apkartai, Ščiurys, Palakajys, and Mateliai. The lake has population of perch, roach, pike and bream  and there are also eels and crayfish. A permit for angling on the lake is required from the Lithuanian Environmental Protection Agency. The lake is also popular with divers. Water tourism
and recreational infrastructure have been created in the lake area.


Lake Kuttara (倶多楽湖, Kuttara-ko) is a nearly circular caldera lake in Shiraoi, Hokkaidō, Japan. It is part of Shikotsu-Tōya National Park. The lake is recognized as having the best water quality in all of Japan. With a transparency of 19 metres (62 ft), the lake ranks second to Lake Mashū according to the Ministry of the Environment.
Resident species of the lake include a salamander species, Ezo salamander (エゾサンショウウオ, Ezo Sanshōuo). Since 1909, Sockeye salmon have been introduced to the lake.


Lake Lauerz (German: Lauerzersee, old spelling: Lowerzer See) is a lake in the Canton of Schwyz, Switzerland.


Its water area varies between 310 ha (766.0 acres) and 360 ha (889.6 acres) (depending on water level), a maximum depth of 14 m (45.9 ft), and a water level elevation above sea level of 447 m (1,466.5 ft).
The lake's water area is divided between the municipalities of Lauerz, Schwyz and Steinen. There are two small islands in the lake, Schwanau and Roggenburg, both of which are in the municipality of Lauerz. The villages of Lauerz, on the southern side of the lake and in its eponymous municipality, and Seewen, at the eastern end of the lake in the municipality of Schwyz, lie on or close to the shore of the lake.
The lake's principal inflow is the Steiner Aa, which flows into the north shore of the lake having passed through the village of Steinen, along with a number of smaller streams. The lake's outflow is at Seewen and takes the form of the Seeweren, a 1.5 km (0.93 mi) long stream. The Seeweren in turn flows into the Muota river, some 2 km (1.2 mi) above that river's mouth on Lake Lucerne.
The 1806 Goldau landslide impacted the lake and caused a tsunami 20 metres (65.6 ft) high. This damaged the villages of Lauerz and Seewen and the island of Schwanau, and partly filled the lake. More recently, floods in 1999 and 2005 have affected lakeside properties, especially in Lauerz, and attempts have been made to control the water level by connecting Lake Lauerz through a tunnel to Lake Lucerne.


Loch Laggan is a freshwater loch situated approximately 6+1⁄2 mi (10.5 km) west of Dalwhinnie in the Scottish Highlands. The loch has an irregular shape, runs nearly northeast to southwest and is approximately 7 mi (11 km) in length. It has an average depth of 68 ft (21 m) and is 174 ft (53 m) at its deepest. The eastern end of the loch features the largest freshwater beach in Britain. Since 1934 Loch Laggan has been part of the Lochaber hydro-electric scheme.  At the northeast end of the loch is the hamlet of Kinloch Laggan.
The loch was surveyed on 2 and 3 of June 1902 by Sir John Murray, T.R.N. Johnston, James Parsons and James Murray and was later charted as part of the Bathymetrical Survey of Fresh-Water Lochs of Scotland 1897-1909.
The A86 road from Spean Bridge to Kingussie follows the loch's north shore. The River Pattack flows into the head of the loch just below the road bridge at Kinloch Laggan. The boundary of the Cairngorms National Park wraps around the head of the loch. A short section of the River Spean connects the natural loch with the reservoir downstream and this river continues westwards below Laggan Dam. Two other substantial watercourses empty into the loch, the Allt Labhrach which drains Lochan na h-Earba which lies southeast of Loch Laggan and Allt Coire Ardair which rises beneath Creag Meagaidh. The remains of an island dwelling lie in the middle of the loch near Ardverikie.
The loch featured in the popular BBC series Monarch of the Glen as Loch Bogle.


Lower Kananaskis Lake is a natural lake that was turned into a reservoir in Kananaskis Country in Alberta, Canada.
Lower Kananaskis Lake is in Peter Lougheed Provincial Park along with the Upper Kananaskis Lake.
The lake is part of a series of natural and man made reservoirs in the Kananaskis and Bow Valleys used for hydro electric power, flood control, and water reserves for the Bow River water users such as the city of Calgary.
The lake is also used for recreational activities, with hiking paths surrounding the lake (and cross-country skiing trails in the winter).


Several campgrounds are located along Kananaskis Lake. Canyon Campground does not have camping spots backing on to the lake, but a lakeside picnic area is available. Lower Lakes Campground does not have spots backing on to shores of Lower Kananaskis Lake either. A network of bicycle trails connects the campgrounds and picnic areas. Most of the year, these are open to the public, but they are closed sometimes due to bears presence in the area. Interlakes Campground is the highest lying campground, and lakeside spots for this campground are available.


Caburgua Lake ([kaˈβuɾɣwa]) is located 23 km northeast of the city of Pucón, in the La Araucanía Region of Chile. Huerquehue National Park lies to the east of the lake. Like Villarrica Lake, it is part of Toltén River basin. During summer the outflow river may dry out but due to high levels of underground infiltration the waterfalls Ojos del Caburgua never run dry.
The lake occupies a glacial valley carved out along the Liquiñe-Ofqui Fault. In the Holocene the valley was blocked by lava flows from the Volcanes de Caburgua.
The lake has recently gained notoriety for the holiday residences of people like former Presidents Sebastián Piñera and Michelle Bachelet.


WikiWeb_Soda Lake (San Luis Obispo County)_0

Soda Lake is a shallow, ephemeral, alkali endorheic lake in the Carrizo Plain in southeastern San Luis Obispo County, California. The lake is located on the southwest side of the northern Carrizo Plain, 103 km (64 mi) east of San Luis Obispo. It can be reached by Soda Lake Road, which runs northwest–southeast between State Route 166 and State Route 58. The lake is at an elevation of 580 m (1,900 ft) and covers an area of about 12 km² (4.6 sq mi).


Loch Eil (Scottish Gaelic, Loch Iall) is a sea loch in Lochaber, Scotland that opens into Loch Linnhe near the town of Fort William.
".. the name of the Chief of Clan Cameron is spelt LOCHIEL, while the name of the loch is spelt LOCH EIL,.."
Loch Eil Outward Bound railway station and Locheilside railway station are both situated on the northern shore of the loch. Achaphubuil is on the southern shore.
Lochiel was a historic place east of Fassfern on the north shore of Loch Eil.  The place was home to Jacobite chieftain Donald Cameron, of Lochiel.
Remnant septs of Clan Chattan such as MacPhail remained in the area after the Clan mostly moved to Inverness. These MacPhails became part of Clan Cameron.

The earliest known residence of the chiefs of Clan Cameron was on Eilean nan Craobh (The island of the trees) just outside the entrance to Loch Eil. They moved from there to Tor Castle in the 17th century and later to Achnacarry. The island has now become part of harbour works.
Loch Eil and Loch Linnhe are joined by narrows at Annat where a paper mill once stood and where there is a now a large timber yard.


The Gangabal Lake also called Haramukh ganga, is a lake situated at the foot of Mount Haramukh in Ganderbal district, north of Srinagar, in Jammu and Kashmir, India. It is an alpine high altitude oligotrophic lake,  home to many species of fish, including the brown trout. This lake is considered sacred in Hinduism, and as one of the home of Lord Shiva. Kashmiri Hindus perform annual pilgrimage called Harmukh-Gangabal Yatra.
The lake has a maximum length of two and a half kilometers and maximum width of one kilometre. It is fed by precipitation, glaciers and springs. The lake water outflows to a nearby Nundkol Lake and then via Wangath Nallah to Sind River.


The Gangbal lake is approached from Srinagar 45 kilometers by road via Ganderbal up to Naranag and then a trek of 15 kilometers upslope leads to the lake, which can be covered by a horse ride or by foot. The gujjar shepherds can be seen during the trek with their flocks of sheep and goats. Another trek (25 kilometers long) leads to the lake site from Sonamarg via the Vishansar Lake crossing three mountain passes Nichnai pass, Gadsar pass and Zajibal pass of an average elevation of 4100 meters. It can also be accessed through a trek from Bandipore via Arin. The trek to the lake Gangabal takes place in an alpine environment, (cut crossing) with meadows, (cut from) and huts of Gujjars with their herds crossing through two passes over 4,000 m to get to the lake Gangabal.


Loch Katrine is a serpentine lake orientated west-north-west - east-south-east, having a length of about 8 miles (13 km), with a maximum width of almost exactly 1 mile (1.6 km) between the mouths of the Letter burn and the Strone burn on the northern shore to a small bay on the opposite shore. The mean breadth, obtained by dividing the area of the loch by its length, is 0.6 miles (0.97 km) being 7.5% of the length.
The waters of the loch cover an area of 3,059 acres (1,238 ha), and it drains a mountainous area, some eight times greater, of about 24,900 acres (10,100 ha). It contains an estimated 27,274,000,000 cubic feet (772,300,000 m³) of water with a mean depth of 99 feet (30 m), being over 40% of the maximum observed depth of 495 feet (151 m).
The surface of the loch is 364 feet (111 m) above sea-level, and so some 645 acres (261 ha) of its bottom lies below sea-level, the deepest part being 131 feet (40 m) below sea-level. In this respect Loch Katrine differs from the other lakes in the Forth Basin, none of which has depth sufficient to bring any portion of their bottoms below the level of the sea.
Loch Katrine forms a single basin, not being divided, like Loch Lomond and Loch Lubnaig, for instance, into separate basins by any important ridges or rises on the bottom. The deepest part is in the centre of the loch, a long narrow depression, with depths exceeding 400 feet (120 m), extending for over 4 miles (6.4 km) from opposite Coilachra to opposite Huinn Dubh-aird, with a maximum width of over one-quarter of a mile (0.40 km); this 400-feet depression has an area of about 515 acres (208 ha), or 17% of the entire superficial area of the loch. The deepest sounding is situated at the very eastern extremity of the 400-feet depression.
The 300 feet (91 m) depression is over 5 miles (8 km) in length, with a maximum breadth of one-third of a mile (0.54 km); it extends from off Coilachra to near Ellen's Isle. The area enclosed between the 300-feet and 400-feet contour lines is about 415 acres (168 ha), or 13% of the entire area of the loch.
The 200 feet (61 m) depression is  five and a half miles (8.9 km) in length and one-half a mile (0.80 km) in maximum breadth, extending from south of Ellen's Isle to near Black Island, where it is separated (by a sounding of 198 feet (60 m)) from a small isolated area, lying between Coilachra and Black Island, one-third of a mile (0.54 km) in length by nearly one-eighth of a mile (0.20 km) broad. The area between the 200- and 300-feet contours is about 510 acres (210 ha), or 17% of the area of the loch.
There are two 100 feet (30 m) depressions, the principal one (6 miles (10 km) long) stretching from close to Ellen's Isle to Black Island, the other extending from Black Island towards the point called Rudha nam Moine, with a total length of over one-half a mile (0.80 km). The area enclosed between the 100- and 200-feet contours is about 670 acres (270 ha), or 22% of the area of the loch.
The 50 feet (15 m)-feet line follows pretty closely the contour of the loch, from Rudha nam Moine into the eastern arms of the loch at the Trossachs, running outside of Black island, Ellen's isle, and the small islands near the shore all round, with a small isolated patch at the junction of the Trossachs arm with the arm leading to Achray Water; it encloses a small shallow, with a beacon on it, opposite the entrance of the Glasahoile. The area between the 50- and 100-feet contours is about 400 acres (160 ha), or 13% of the area of the loch, while the area between the coast-line and the 50-feet contour is nearly 550 acres (220 ha), or 18% of the loch area; so that 82% of the floor of the loch is covered by over 50 feet (15 m) of water.


Loch Katrine (listen ; Scottish Gaelic: Loch Ceiteirein [l̪ˠɔx ˈkʲʰeʰtʲɪɾʲɛɲ] or Loch Ceathairne) is a freshwater loch in the Trossachs area of the Scottish Highlands, east of Loch Lomond, within the historic county and registration county of Perthshire and the contemporary district of Stirling. The loch is about 8 miles (13 km) long and 1 mile (1.6 km) wide at its widest point, and runs the length of Strath Gartney (Gaelic: Srath Ghartain). It is within the drainage basins of the River Teith and River Forth.
It is a popular scenic attraction for tourists and day-visitors from Glasgow and nearby towns; fly and boat fishing for trout are permitted on the loch from spring to autumn. It also serves as a reservoir for the water supply of the Glasgow conurbation, some 30 miles (48 km) south, being connected by two aqueducts constructed in 1859.
It is the fictional setting of Sir Walter Scott's poem The Lady of the Lake and of the subsequent opera by Gioachino Rossini, La donna del lago.


Röblinsee is a lake in the Mecklenburg Lake District, in Germany. It is situated in the district of Oberhavel in the state of Brandenburg, and lies immediately to the west of the town of Fürstenberg. The lake has an east–west orientation, and is about 2 kilometres (1.2 mi) long and up to 0.5 kilometres (0.31 mi) wide.
The navigable River Havel flows through the Röblinsee, entering it via a 5.4 kilometres (3.4 mi) channel from the Ziernsee. The river exits the lake through a short channel and lock in the centre of Fürstenberg, before entering the linked lakes of Baalensee and Schwedtsee. Navigation is administered as part of the Obere–Havel–Wasserstraße.


Manasbal Lake is a freshwater lake located in Safapora area of Ganderbal District in Jammu and Kashmir, India. The name Manasbal is said to be a derivative of Manasarovar. Lake is encircled by four villages viz., Jarokbal, Kondabal, Nesbal (also called Kiln place, is situated on the north-eastern side of the lake) and Gratbal. The large growth of lotus (Nelumbo nucifera) at the periphery of the lake (blooms during July and August) adds to the beauty of the clear waters of the lake. The Mughal garden, called the Jaroka Bagh, (meaning bay window) built by Nur Jahan overlooks the lake.
The lake is a good place for birdwatching as it is one of the largest natural stamping grounds of Aquatic birds in Kashmir and has the sobriquet of "supreme gem of all Kashmir Lakes". The rootstocks of lotus plant which grows extensively in the lake are harvested and marketed, and also eaten by the local people.


The lake is surrounded by the Baladar mountains on the east, by an elevated plateau known as 'Karewa' comprising lacustrine, fluviatile and loessic deposits on the north and bounded by the Ahtung hills in the south, which are used for limestone extraction.
Along the course of the Jhelum River, the Manasbal Lake falls under the third series of high altitude lakes of the Himalayas (designated with respect to their origin, altitudinal situation and nature of biota they contain) as the valley lakes (Dal, Anchar Lake, Manasbal etc.) situated at the altitudinal zone of 1,585–1,600 m (5,200–5,249 ft); the other two  types being the high altitude wetlands (altitude 1,585–4,000 m or 5,200–13,123 ft amsl) of the second series of  lakes (Nilnag) in the lower fringes of Pir Panjal ranges right in the midst of pine forests, and the glaciated lakes of the first series situated on the inner Himalayas between 3,000–4,000 m (9,800–13,100 ft) amsl (Alipathar, Sheshnag, Kounsarnag, Tar Sar, Marsar, Vishansar, Gangbal, Kishan Sar, Kyo Tso, Pangong Tso, etc.) which have probably originated during the third Himalayan glaciation. A fissure is reported to be running from east to west at the centre of the lake.


The drainage basin for the lake, covering an area of 10 km² (3.9 sq mi), has no major inlet channels and is thus fed mainly by precipitation (rain and snow fall) and springs (more than 1,200 springs). Lake water outflows to the Jhelum River through a regulated outflow channel. The lake is the source of water for fishing and for obtaining food and fodder plants.
The lake not only provides source of water but also offers facilities for navigation and transportation, fisheries, harvesting of economically useful plants, sightseeing, tourism and recreation.


The fauna recorded in the lake are the zooplankton, benthos and fish. The economically important fishes reported are:
Schizothorax niger, S. esocinus, Cyprinus carpio specularis+, C. carpio communis+ and Neomacheilus latius.
Note:+ considered economically important
Cyprinus, an exotic species, has proliferated extensively after its introduction in 1956. A decline in the population of indigenous species due to rapid changes in the environment was reported.


The weather is pleasant in the months of May and August, when the lake offers water skiing sport, which is now becoming an increasingly popular activity in many rivers and lakes in India. Jammu & Kashmir Tourism Department (JKTD) provides essential water skiing equipment and trained instructors to adventure seekers. The lake's surface sheen and its long length and width attract tourists to water skiing sport. However, the noise and turbulences of waterskiing boats will totally change the environment of this last quiet lake and could risk to take away one of its main attractions: Peace. There is still a discussion going on whether or not a more environmentally sensitive form of sustainable tourism would be more appropriate for this special lake – to not turn it into a second Dal Lake.


Lago di Caldonazzo is a lake in Trentino, Italy. At an elevation of 449 m, its surface area is 5.38 km². It is located in the valley communities of Alta Valsugana e Bersntol.
Water sports like the canoe, the sail, wind surfing and water skiing is famous on the lake. The lake has played an important role; it was, and still is, the "training ground" for Thomas Degasperi, water skier Trentino specialist in the discipline slalom, current European and world champion.


Cultus Lake is a natural lake in Deschutes County in the U.S. state of Oregon. Formed by a glacier, it is located in the high Cascade Range in the Deschutes National Forest. The name is from the Chinook Jargon and means variously bad or worthless, or simply "in vain".
In the early 19th century, the lakes in this area abounded with beavers. The earliest explorers to this area were primarily on a quest for furs.


Cultus Lake lies at the base of the Cultus Mountain. The lake itself is natural and is 211 feet (64 m) at its deepest point and about 2 miles (3.2 km) long. Several species of fish inhabit the lake, including rainbow trout, lake trout (mackinaw) and brook trout.
The lake also receives several streams inhabited by younger fish. The largest is Winopee Creek, which enters through the marsh on the northwestern side, a popular fly fishing spot. Two miles south is a smaller lake called Little Cultus Lake. The two lakes are divided by Cultus Mountain.  The lake empties to the east via Cultus Creek, which flows into Crane Prairie Reservoir.
The area around Cultus Lake is known for its large ponderosa pine, Douglas-fir and western white pine, sometimes rising to 120 feet (37 m) tall. However, according to the U.S. Fish and Wildlife Service, the large pines are being weakened by competing understory fir trees and mountain pine beetle attacks. If the trend is not reversed, there will be a shift in tree species (and tree size) from pine and Douglas-fir to white fir.
The service recommends the selective thinning of white fir understory trees around selected ponderosa and western white pine to increase light, and the availability of nutrients, allowing the selected pines to grow more vigorously and increase their resistance to bark beetles.


Cultus is a recreational lake and is also popular for water skiing, sailing, jet skiing and boating.
The lake has a resort with 23 cabins and a lodge with a restaurant and a store. There are also three other campsites for people to set up tents or park RVs.


The Oregon Department of Fish and Wildlife manages the lake for the natural and hatchery production of rainbow trout and brook trout.  They also manage the natural production of Mountain Whitefish and lake trout.


Plauer See  (German, literally Lake of/near Plau) is a lake in Mecklenburg-Vorpommern, Germany, located at 53°27′57″N 12°18′27″E. Its surface is approximately 38.4 km² and its maximum depth is 25.5 metres (84 ft).


The Plauer See is flowed through by the river Elde from east to west and is part of the "Bundeswasserstraße Müritz-Elde-Wasserstraße" with waterway class I; the "Wasserstraßen- und Schifffahrtsamt Lauenburg" is responsible. The Global Nature Fund awarded the water body the title Lebendiger See des Jahres 2011.
With an area of 38.4 km², the Plauer See is the third largest lake in Mecklenburg-Vorpommern and the seventh largest in Germany. It has a north–south extension of around 14 kilometres, a maximum width of 5 kilometres and an average depth of 6.8 metres. It has connections via the Elde to the Fleesensee, the Kölpinsee and the Müritz in the east and to the river Elbe in the west. On the western shore of the Plauer See lies the eponymous town of Plau am See, which is also the centre of tourism in this region. There are many tourist facilities around the Plauer See, such as the camping sites located on the eastern and northern shores, near the town of Plau and on the island of Plauer Werder in the north. The lake is surrounded by a (largely still unpaved) circular cycle path.
Lake Plauer was called Cuzhin or Kuzin in the 12th century, like the settlement and castle of the same name, Kutin or Kutsin - today's Quetzin - on the western shore of the lake. Only later was the lake given the name of the town of Plau, which lies on the shore.
The north-western part of the lake lies in the "Naturschutzgebiet Nordufer Plauer See".


Blackbeck Tarn is a small tarn in Cumbria, England, situated near the summit of Haystacks in the Buttermere Valley. At an elevation of 486 m (1,594 ft), the lake has an area of 0.95 hectares (2.3 acres) and measures 183 m × 80 m (600 ft × 262 ft), with a maximum depth of 2.5 m (8.2 ft).


Taudaha Lake is a small lake in the outskirts of Kathmandu, in Nepal. The name comes from a combination of Newari words 'Ta', meaning snake and 'Daha', which means lake.


Various species of birds have been recorded out of which many are residents, a few are summer migrants and rest are winter migrants. Black kite, Black drongo, Cattle egret, Oriental magpie robin, Common myna, Jungle crow, Rose-ringed parakeet, White-throated kingfisher and Red-vented bulbul are some of the resident birds. Barn swallow and Indian cuckoo are summer visitors. Winter migrants include the Great cormorant, ruddy shelduck, Northern shoveler, Mallard duck, Gadwall, Eurasian coot, Northern pintail and common teal.
There are many species of fishes in the lake. It is well known for large carps. Common carp, Silver carp, Grass carp, Bighead carp and colourful carps have been introduced in the lake. These non-native species have disrupt the ecosystem and are out-competing the native species. Native fish species include catfishes and snakeheads.
Mammals such as Golden jackal, Indian grey mongoose and several rodents are found around the lake.
Checkered keelback and Oriental garden lizard are frequently sighted reptile species.


Lake Sempach (German: Sempachersee) is a lake in the canton of Lucerne, Switzerland. Its area is about 14.5 km² (5.6 sq mi) and its maximum depth is 87 m (285 ft).
A 50-metre-large (160 ft) island named Gamma Insel is located east of Sursee.
Many inhabitants of local areas swim, boat, paddle, and fish in Lake Sempach, due to its ease of accessibility.


Miscou Island Lighthouse is an 24.3-metre (80 ft)-tall landfall lighthouse located on the North-Eastern tip of Miscou Island, at the entrance of the Chaleur Bay. It was built in 1856 and currently in use by the Canadian Coast Guard who owns the lighthouse, the land it is on, and also maintains it.  It was built due to the shipwrecks that happened each year that could be prevented by a lighthouse.  James Murray from Newcastle won the bid to construct the lighthouse.  It is a federal Heritage Building that is open to the public to explore.  In 2009 a parking area, washrooms, picnic area and a deck around the lighthouse was added.
The light's characteristic is a single green flash that occurs every five seconds, emitted at a focal plane height of 14 metres (46 ft).  It has a third-order Fresnel lens.  The original lens was shipped from England and arrived on October 10, 1856, and the person in charge of the only other lighthouse on the northern coast of New Brunswick, William Hay, was sent to oversee the installation.
Smoke conductors were installed in 1860 due to the fact that the calm weather could not sufficiently clear the smoke from the lantern room.  In 1874 a building was built which contained a steam fog whistle that had blasts of 5 seconds that were separated by 25 seconds of silence.
In 1946 the lighthouse was moved 200 feet inland.


Hel Lighthouse is an active lighthouse in the town of Hel, Pomeranian Voivodeship in Poland.  It is situated at the eastern tip of the Hel Peninsula and guides ship traffic into Gdańsk Bay and the Bay of Puck.


The lighthouse on Hel has its origins in the 16th century when a fire was lit on the church tower at a height of 116 feet to guide ships. The structure burned down. In 1638 locals asked Gdańsk authorities to build a lighthouse on the peninsula. After deliberation, a wooden structure was erected circa 1640, with a range of about 6 miles. In 1667 it burned down, too.
Two further attempts at construction failed as well. However, seafaring in this area of the Baltic remained hazardous, so around 1790 another effort was made. A site was allocated, including a lighthouse-keeper's residence. The light was to be lit every day.
Though effectiveness improved, the lighthouse soon faced the problem of being obscured by growing trees. The construction of the first brick lighthouse started in 1806. Due to civil wars the effort dragged on until 1826.
The brick lighthouse wasn't high enough and ships continued to sink between Jastarnia and Hel. A cannon was placed at the lighthouse, fired every four minutes, as a sound signal. This continued until the gunner died in 1910. A stone commemorates the event to this day.
More improvements followed. The light source switched to a paraffin lamp and the structure was renovated. Electric light was installed in 1938 in the form of a 3000 watt bulb. During World War II Germans decided to take down the structure, since it presented a perfect target for air raids.
In 1942 Germans ordered locals to erect a new lighthouse. It stood 10 meters to the southeast from the old one (now detonated). The new structure was modern, powered by electricity, and it's been in operation to this day.
The 40.8-meter tower is painted red and octagonal in shape. The light source is a 1000 watt bulb, set 38.5 meters above sea level, with a range of 17 miles. The lighthouse is also a part of an air traffic control system.
The lighthouse is a tourist attraction and open to the public during summer. Apart from the lighthouse itself, a few keeper houses remain, dating back to 19th century. Facing west, inland, one can see the Swedish Hill with an old lighthouse built during World War II to replace the one destroyed in Hel at the same time.


The lighthouse was established in 1782 atop the "French Castle", a structure still located within Old Fort Niagara. The current tower was first lit in 1872, having been removed from the French Castle to allow for more room for officer's quarters.  The light was deactivated in 1996, having been replaced by a light beacon at the US Coast Guard Station Niagara.
The foundation was natural/emplaced and the lighthouse was constructed out of limestone with a brick lining.  The tower is octagonal in shape with a black lantern.  The original lens was a fourth order Fresnel lens installed in 1859
National Register Status: LISTED; Reference #84002809
Name of Listing: FORT NIAGARA LIGHT (U.S. COAST GUARD/GREAT LAKES TR)
Part of Old Fort Niagara National Historic Landmark;  First two towers constructed on the fort; Third (current) tower constructed south of fort; Tower replaced by modern beacon in order to save trees obstructing lantern in 1993.


Punta Carena Lighthouse (Italian: Faro di Punta Carena) is an active lighthouse, located on the island of Capri on the head of the same name, about 3 kilometres (1.9 mi) southwest of Anacapri. The lighthouse has been active since 1867; its construction began in 1862.


It consists of an octagonal prism brick tower with lantern and gallery, above a two-story building. The lighthouse was repainted recently and is now white with red vertical stripes, and the keeper's house in red.
The lighthouse has a rotating view that emits  white light flashes every 3 seconds. The focal plane is located at 73 meters above sea level. The lighthouse has a range of 25 nautical miles (about 46 km), and is therefore defined as an offshore lighthouse. It is a 28 m (92 ft) octagonal masonry tower on a two-story house.


Old Colombo Lighthouse or Colombo Fort Clock Tower is a clock tower and was a lighthouse in Colombo. The lighthouse is no longer operational, but the tower remains and functions as a clock tower. It is located at the junction of Chatham Street and Janadhipathi Mawatha (formerly Queens Road) in Colombo fort.


The tower was constructed as a clock tower in 1856-57 and completed on the 25 February 1857. The tower was designed by Emily Elizabeth Ward, the wife of Governor Sir Henry George Ward (1797 – 1860). The construction was undertaken by the Public Works Department, under the supervision of Mr John Flemming Churchill (Director General of Public Works). The 29-metre-high (95 ft) tower was the tallest structure in Colombo at that time. The original clock was commissioned for £1,200 in 1814 by the then Governor Sir Robert Brownrigg (1759 – 1833) but was kept in a warehouse, due to economic reasons, until 1857 when it was finally installed.
The lighthouse was deactivated after its light became obscured by nearby buildings and was decommissioned on 12 July 1952. The modern Galle Buck Lighthouse was erected on Marine Drive as its replacement.


The original Colombo lighthouse was located on a bastion on the ocean edge of the fort, was a neo-classical structure, with a 23 m (75 ft) wooden light tower rising from a two-storey circular brick building and surrounded by an elaborate colonnade.  It was erected in 1829 and subsequently demolished with the removal of the fort ramparts between 1869 and 1871.
The clock mechanism was constructed by the renowned English clockmakers, Dent, who were also responsible for manufacturing the clock ('Big Ben') at Westminster Palace in 1852. The clock tower was formally commissioned on 25 March 1857. The bells in the clock tower consisted of a main bell of approx. 250 kg (550 lb) and two auxiliary bells of 152 kg (335 lb).
The navigational light was moved to the tower in 1867. The clockwork operated revolving dioptric light was constructed by Chance Brothers. The height of the focal plane above sea-level was 140 m (460 ft) and the light was visible to an eye elevated 61 m (200 ft) above sea level at a distance of 27 km (17 mi) in clear weather. The light was a triple flash at intervals of 30 seconds, each flash being of one second duration, and each long eclipse of 18 seconds duration. The light was lit using kerosene oil. In 1907 it was converted to gas. In 1933 it was replaced with a 1,500 candle power light powered by electricity.
In October 1913, the clock had to be replaced with the current clock, which has a six-foot dial glazed with opal glass for illumination and the clock tower was re-inaugurated on 4 April 1914.


The Hudson–Athens Lighthouse, sometimes called the Hudson City light, is a lighthouse located in the Hudson River in the state of New York in the United States. The light is located between Hudson and Athens, closer to the Hudson side. Constructed in 1874, it marks a sandy ridge known as Middle Ground Flats and also acts as a general aid to navigation of the river. The station is built on a granite caisson with a unique shape designed to protect it from ice floes and river debris. The dwelling is constructed in the Second Empire architectural style,
with a mansard roof. It is considered to be virtually a twin of the Stepping Stones Light in Long Island Sound, which was constructed just a few years later.


The station's beacon was originally lighted by Henry D. Best, the station's first lightkeeper, on November 14, 1874. It was upgraded to a fifth-order Fresnel lens in 1926, and the station was fully automated on  November 10, 1949. In 1967, the Hudson River Valley Commission, led by Nelson A. Rockefeller, suggested that certain lighthouses owned by the United States Coast Guard be turned over to not-for-profit historical groups to ensure their preservation and upkeep. Hudson–Athens was the first station to be tried through such a program, and on February 15, 1984, a 20-year lease was signed between the Coast Guard and the Hudson–Athens Lighthouse Preservation Society (HALPS). In 2000, title to the station was turned over permanently to HALPS. Today, the Preservation Society conducts occasional tours of the station, which is being restored to its condition as it would have been in the 1930s.
The Lighthouse was documented by the Historic American Buildings Survey (HABS) as survey number NY-6286. There are 9 architectural drawings available in the survey.
The Hudson–Athens Lighthouse is shown on the NOAA Chart 12347.


Helnes Lighthouse (Norwegian: Helnes fyr) is a coastal lighthouse located on the northeastern coast of the island of Magerøya in Nordkapp Municipality in Troms og Finnmark county, Norway.  The lighthouse sits on the western side of the mouth of the large Porsangerfjorden, about 12 kilometres (7.5 mi) east of the village of Kamøyvær and about 13 kilometres (8.1 mi) northeast of the town of Honningsvåg.  The lighthouse was established in 1908, destroyed during World War II in 1944, rebuilt from 1946–1948, and automated in 2004. A radio beacon was established in 1955 and it emits a racon signal that is a Morse code letter N (– •).
The 10-metre (33 ft) tall white concrete tower has a light on top at an elevation of 37.5 metres (123 ft) above sea level.  The 1,371,000-candela light emits two white flashes every 30 seconds.  The light can be seen for up to 13.5 nautical miles (25.0 km; 15.5 mi) in all directions.


Neuland Lighthouse (German: Leuchtturm Neuland) is a lighthouse in the north German state of Schleswig-Holstein on the Baltic Sea coast that was in service from 1918 to 1996. It stands on the western shore of Hohwacht Bay about 1 kilometre north of the village of Behrensdorf.


The lighthouse was built in 1915/16 and taken into service in 1918. It is built of brick and is 40 metres high. The light is 40 metres above sea level. The original red and white exterior paint was removed in 1985 when the tower underwent a modernisation.
The original lens was a Fresnel lens with a focus of 400 m. It was replaced by a rotating mirror optic in 1996 when the regular light was deactivated and the tower was transferred to the German Navy. The tower has since been used as a warning light displaying red and yellow signals when live firing is conducted in the military training grounds at Hohwacht Bay.
The lighthouse is displayed in the arms of Behrensdorf and was featured on a German stamp in 2006.


Ocracoke /ˈoʊkrʌkoʊk/  Light was built in Hyde County, on Ocracoke Island, North Carolina in 1823 by Massachusetts builder Noah Porter.  The lighthouse stands 75 feet (23 m) tall.  Its diameter narrows from 25 feet (7.6 m) at the base to 12 feet (3.7 m) at its peak.  The lighthouse was built to help guide ships through Ocracoke Inlet into Pamlico Sound.
In 1864, Confederate troops dismantled the fourth-order Fresnel Lens, but Union forces later restored it.
Ocracoke Light is the oldest operating light station in North Carolina and the second oldest lighthouse still standing in the state. The lighthouse was automated in 1955. During the summer months when there is a U.S. National Park Ranger on duty, visitors may access the base of the lighthouse.  Access to the top of the lighthouse is not allowed due to the simple steel spiral staircase being safe only for maintenance activity.
However, this is not the original staircase; the original staircase was a wooden step spiral built into the inside of the exterior wall. This was removed during the 1950s due to excessive rotting to the boards and a lacking necessity for a substantial staircase because of the automation of the light. The wooden stairs were removed and the holes in the all-brick lighthouse were cemented closed.
The lighthouse was added to the National Register of Historic Places in 1977 as Ocracoke Light Station.


The Watchet Harbour Lighthouse is a marine navigational aid marking the entrance to a Marina within the  town of Watchet, in Somerset, England.


In the 1850s the West Somerset Mineral Railway was nearing completion. Parts of the harbour had fallen into disrepair, and boats were beached and loaded direct from carts brought onto the foreshore. It was recognised that improvements were needed for the sake of the prosperity of the town and the export of iron ore from ironstone mines in the Brendon Hills to Newport and thence to Ebbw Vale for smelting. The Watchet Harbour Act was passed in 1857, placing it under the control of Commissioners; they built a new east pier and rebuilt the west pier; the work was finished in 1862, and 500 ton vessels could enter the harbour. The west pier on which the lighthouse stands was constructed in 1860, at the same time as the current east pier, by Hennets of Bridgwater, and rebuilt in 1905.
Tenders for the new lighthouse at the end of the harbour wall were placed in 1860. Three bids were received. The design by Isambard Kingdom Brunel was rejected in favour of one by James Abernethy. This was built by Hennet, Spinks and Else of Bridgwater for £75. The cast iron structure was topped with an oil lamp.
In September 2012, Princess Anne unveiled a plaque to commemorate the 150th anniversary of the lighthouse.


The cast iron lighthouse is approximately 22 feet (6.7 m) in height and has a red hexagonal tower with white lantern, and green lens.
The lighthouse is a harbour navigation mark and does not emit a flashing light associated with traditional lighthouses. Instead it displays a fixed green luminaire marking the starboard (right hand side) approach to the marina.


The Ameland Lighthouse, commonly known as Bornrif, is a lighthouse on the Dutch island Ameland, one of the Frisian Islands, on the edge of the North Sea. It was built in 1880 by order of William III of the Netherlands. It was designed by Dutch lighthouse architect Quirinus Harder and built by the foundry Nering Bögel in Deventer. The individual segments were shipped to Ameland and welded together on-site.
After World War II a new, weaker lamp was installed, which was replaced by a stronger lamp in 1952. The lighthouse is a Rijksmonument since 1982. Since the end of 2004 it is owned by Ameland, and it was opened for tourists in 2005. The tower has a space for exhibitions.
The lighthouse is 55 metres (180 ft) tall and has 15 floors, with a staircase with 236 steps. The optical installation came from the former Westhoofd Lighthouse in Ouddorp.


Avery Point Light or Avery Point Lighthouse is a lighthouse in Groton, Connecticut, United States, on the Avery Point Campus of the University of Connecticut. Although construction was completed in March 1943, the lighthouse was not lit until May 1944 due to concerns of possible enemy invasion. Its original light consisted of eight 200-watt bulbs that were later replaced by a flashing green light in 1960. It was deactivated on June 25, 1967, when the United States Coast Guard Training Station moved to Governors Island. It is officially listed as the last lighthouse built in the state; the only other claimant is the replica Mystic Seaport Light.
The lighthouse deteriorated until it was declared a hazard by the University of Connecticut in 1997. A restoration effort was launched in 1999 through the American Lighthouse Foundation (ALF) and in 2000 by a new local chapter, the Avery Point Lighthouse Society. The restoration of the lighthouse began in 2001 and was completed in 2006, requiring a replica lantern and extensive structural repairs and replacement of the crumbling of the blocks. Two bills for $150,000 and $100,000 were appropriated and used to complete the restoration. The relighting and re-dedication of the lighthouse was held on October 15, 2006. The lighthouse was listed on the National Register of Historic Places in 2002.


The land upon which Avery Point Light was constructed was owned by Morton F. Plant's estate; his Branford House is located several hundred feet away. Twenty four years after Plant's death the estate was sold to the state of Connecticut before being transferred to the U.S. Coast Guard. The Coast Guard's deed required the construction and maintenance of beacon lights or other navigational aids as part of the Coast Guard's new training facility. The Avery Point Light was named for Captain James Avery of New London, Connecticut.
The Avery Point Light was designed by Alfred Hopkins and Associates to be a 41-foot (12 m) octagonal tower. Construction of the tower was completed in March 1943; it is built of brown concrete blocks and topped with an octagonal wooden lantern. During the restoration effort, it was discovered that six different types of concrete blocks were used in the construction. The tower has a total of five windows, with two facing south and one for the north, east and west. The lantern gallery deck is constructed of concrete and lined with thirty two Italian marble balusters, originally imported from Italy around 1900. The interior has an iron ladder, originally wooden, that leads up to the watchroom level. The lighthouse design and masonry tower have Colonial Revival elements. It is the last lighthouse built in the state of Connecticut as an official navigational aid.


Ned Point Light is a historic lighthouse on Ned's Point Road in Mattapoisett, Massachusetts. The lighthouse was built in 1838 at a cost of approximately $5,000, and named after Ned Dexter, a local farmer. Under the supervision of a local builder, Leonard Hammond, the lighthouse was constructed with a birdcage-style lantern similar to Bird Island Light found in Marion, Massachusetts. The stone used for the lighthouse was all locally sourced, with most of it originating from nearby beaches. Inside, there are 32 granite steps that are cantilevered to the outside wall without the use of mortar. The original lantern used 11 whale oil lamps, each with its own parabolic reflector. The lamps and reflectors were replaced by a fifth order Fresnel lens in 1857, along with a change to an octagonal lantern. The Great Blizzard of 1888 significantly damaged the keeper's stone house, resulting in it being demolished and the building of a wooden replacement.
Following the lighthouse's automation in 1923, the keeper's house became unnecessary. The original stone keeper's house was loaded on a barge and taken to Wing's Neck Light in Bourne, Massachusetts. The lighthouse was deactivated from 1952, but remained under control of the US Coast Guard. Following modernization in 1961, the lighthouse was reactivated in 1961 with its current 6-second isophase. The lighthouse was added to the National Register of Historic Places in 1982, and approved in 1988.


Kõpu Lighthouse (Estonian: Kõpu tuletorn) is one of the best known symbols and tourist sights on the Estonian island of Hiiumaa. It is one of the oldest lighthouses in the world, having been in continuous use since its completion in 1531. The lighthouse is quite unique with its shape and an exception among lighthouses because it has gone through all the stages from a medieval landmark up to a modern electrified lighthouse.
The lighthouse marks the Hiiu Shoal (Estonian: Hiiu madal, Swedish: Neckmansgrund) and warns ships away from the shoreline. Light from Kõpu Lighthouse can be used for navigation as far as 26 nautical miles (48 km; 30 mi) away.
Kõpu Lighthouse was previously known by its Swedish name, Övre Dagerort.


The lighthouse is built at the top of the highest hillock of Hiiumaa island, Tornimägi (English: Tower Hill, 68 metres (223 ft)). The height of the building itself is 37.7 metres (124 ft), and the light is 103.6 metres (340 ft) above sea level, making it the highest coastal light on the Baltic Sea.
Kõpu Lighthouse has a shape of a square prism with massive buttresses in the directions of principal divisions of the compass. The tower is laid solely of stone up to the height of 24 metres (79 ft). The outside layer of the walls is supported by lime (and nowadays also cement) mortar, with the body itself built without mortar.
The body of the tower contains roughly 5,000 cubic metres (6,500 cu yd) of stone, with its total weight reaching 12,000 tonnes (26,000,000 lb). Local limestone and glacial erratic stones were used as building material.
Originally, the tower was solid stone without any rooms and no light was burned at it; when it was equipped with light, the top of the lighthouse was reached using external wooden stairs, which were later replaced with iron ones. During reconstruction in the 1800s, a stairway and two rooms were cut into the tower.


A new light system was bought at the 1900 Paris World Fair, for three million gold rubles. The new apparatus (including the light chamber) was made by Sautter, Marlé & Co. It used a kerosene lamp with an incandescent mantle. A heavy cast iron system floated and rotated in a bath of mercury, which acted as a bearing. The bath contained roughly 500 kilograms (1,100 lb) of mercury. The poisonous mercury from the lighthouse was used for decades by children in the surrounding villages for playing.
The light system was set in rotation by a suspended 400 kilograms (880 lb) load; it needed to be rewound every two hours. It was installed during repairs of 1901.
German bombers targeted the lighthouse in August 1941, though only the lantern structure and optical system were destroyed.
After World War II, various optical systems were tested. Kohler generators were installed in 1949 along with the stationary electric light system. A new rotating light system (EMV-3) was installed in 1963, making the lighthouse fully automated. It was in use until 1982, when an experimental EMV-930M system (made in Ukraine) was installed. The rotation mechanism of the optical system was a novel solution – there are no electric motors; it uses a revolving magnetic field instead. The optics brought a six to eight hundredfold increase to the efficiency of the light radiated by a 1 kW quartz lamp.
Due to deterioration, the lighthouse underwent frequent repairs; major repairs were in completed in 1957 and 1970. During the repairs in years 1978–81 on the occasion of the 450th anniversary of the lighthouse, it was covered with a reinforced concrete shell and perchlorovinyl paint. As there was no white colour available, yellow was used. The paint blocked the way for humidity to escape from the body of the tower and water collecting in the inner surface of the cement mortar, freezing and melting, started to damage the already old and degraded lime mortar. By the mid-80s cracks appeared in the surface of the lighthouse and pieces of the cement mortar and smaller stones started falling off. During 1987 and 1988 two corners of the tower collapsed and emergency restoration was started. During the years 1989–90, to prevent collapsing of the lighthouse, a 15 centimetres (5.9 in) thick reinforced concrete shell was built to support the foundation and walls up to the top of the buttresses. The tower was painted with whitewash. Air channels were left in the concrete for ventilating the structure.
The lantern room of the lighthouse was renovated in 2001 and the tower was last repainted, with whitewash, in 2012. In 2020 a new powerful LED light source was installed in the existing lantern along with a new electronic control system. As of 2020, it is the most powerful LED-lighthouse light in the world with an intensity of 2,100,000 candela.
