Thirlmere is a reservoir in the Borough ___MASK1___ Allerdale in ___MASK2___ and the English Lake District . It runs roughly south to north and is bordered on the eastern side by the A591 road and on the western side by a minor road . It occupies the site ___MASK1___ two former natural lakes ( or - on a different analysis - a single lake with a narrow fordable waist ). In the 19th century Manchester Corporation constructed a dam at the northern end , raising the water level , flooding the valley bottom , and creating a reservoir to provide the growing industrial city ___MASK1___ Manchester with water supplies via the 96 mile - long Thirlmere Aqueduct . The reservoir and the aqueduct still provide water to the Manchester area . Meltwater is water released by the melting ___MASK1___ snow or ice , including glacial ice , tabular icebergs and ice shelves over oceans . Meltwater is often found in the ablation zone ___MASK1___ glaciers , where the rate ___MASK1___ snow cover is reducing . Meltwater can be produced during volcanic eruptions , in a similar way in which the more dangerous lahars form . Helvellyn (" ___MASK69___ yellow moorland ") is a mountain in the English ___MASK12___ , the highest point ___MASK1___ the Helvellyn range , a north - south line ___MASK1___ mountains to the north ___MASK1___ Ambleside , between the ___MASK26___ ___MASK1___ Thirlmere and Ullswater . A glacier ( or ) is a persistent body ___MASK1___ dense ice that is constantly moving under its own weight ; it forms where the accumulation ___MASK1___ snow exceeds its ablation ( melting and sublimation ) over many years , often centuries . Glaciers slowly deform and flow due to stresses induced by their weight , creating crevasses , seracs , and other distinguishing features . They also abrade rock and debris from their substrate to create landforms such as cirques and moraines . Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface ___MASK1___ bodies ___MASK1___ water . Ullswater is the second largest lake in the English ___MASK12___ , being approximately nine miles ( 14 . 5 kilometres ) long and 0 . 75 miles ( 1 , 200 m ) wide with a maximum depth ___MASK1___ slightly more than . Many regard Ullswater as the most beautiful ___MASK1___ the English ___MASK26___ ; it has been compared to Lake Lucerne in Switzerland and it is a popular tourist destination . It is a typical ___MASK12___ narrow " ribbon lake " formed after the last ice age when a glacier scooped out the valley floor and when the glacier retreated , the deepened section filled with meltwater which became a lake . A total ___MASK1___ three separate glaciers formed the lake . The surrounding mountains give Ullswater the shape ___MASK1___ a stretched ' Z ' with three distinct segments ( or ' reaches ') that wend their way through the surrounding hills . Lake ___MASK42___ ( literally " Lake ___MASK1___ the Four Forested Settlements ", ) is a lake in central Switzerland and the fourth largest in the country . ___MASK91___ , officially the Swiss Confederation , is a federal republic in Europe . It consists ___MASK1___ 26 cantons , and the city ___MASK1___ Bern is the seat ___MASK1___ the federal authorities . The country is situated in Western - Central Europe , and is bordered by Italy to the south , France to the west , Germany to the north , and Austria and Liechtenstein to the east . ___MASK91___ is a landlocked country geographically divided between the Alps , the Swiss Plateau and the Jura , spanning an area ___MASK1___ . While the Alps occupy the greater part ___MASK1___ the territory , the Swiss population ___MASK1___ approximately eight million people is concentrated mostly on the plateau , where the largest cities are to be found : among them are the two global cities and economic centres Zürich and Geneva . An ice age is a period ___MASK1___ long - term reduction in the temperature ___MASK1___ Earth ' s surface and atmosphere , resulting in the presence or expansion ___MASK1___ continental and polar ice sheets and alpine glaciers . Within a long - term ice age , individual pulses ___MASK1___ cold climate are termed " glacial periods " ( or alternatively " glacials " or " glaciations " or colloquially as " ice age "), and intermittent warm periods are called " interglacials ". Glaciologically , " ice age " implies the presence ___MASK1___ extensive ice sheets in both ___MASK56___ and southern hemispheres . By this definition , we are in an interglacial period  the Holocene  ___MASK1___ the ice age that began 2 . 6 million years ago at the start ___MASK1___ the Pleistocene epoch , because the Greenland , Arctic , and Antarctic ice sheets still exist . The ___MASK12___ , also known as the ___MASK26___ or Lakeland , is a mountainous region in North - West England . A popular holiday destination , it is famous for its ___MASK26___ , forests and mountains ( or " fells ") and its associations with the early 19th century writings of William Wordsworth and the other Lake Poets . A lake is an area ___MASK1___ variable size filled with water , localized in a basin , that is surrounded by land , apart from any river or other outlet that serves to feed or drain the lake . ___MASK26___ lie on land and are not part ___MASK1___ the ocean , and therefore are distinct from lagoons , and are also larger and deeper than ponds , though there are no official or scientific definitions . ___MASK26___ can be contrasted with rivers or streams , which are usually flowing . Most ___MASK26___ are fed and drained by rivers and streams . Ambleside is a town in ___MASK2___ , in North West England . Historically within the county of Westmorland , it is situated at the head of Windermere , England ' s largest water . The town is within the Lake District National Park . The Helvellyn range is the name given to a part ___MASK1___ the Eastern Fells in the English Lake District , " fell " being the local word for " hill ". The name comes from Helvellyn , the highest summit ___MASK1___ the group . Glenridding is a village located at the southern end ___MASK1___ Ullswater , in the English Lake District . The village is popular with mountain walkers who can scale England ' s third highest mountain , Helvellyn , and many other challenging peaks from here . The village has accommodation including two Youth Hostels and camping sites . There is also a tourist information centre , Ullswater Information Centre . Glenridding is in the civil parish ___MASK1___ Patterdale . Each year , on Easter Monday , a duck race is organised by the local mountain rescue team to raise funds . On 6 December 2015 , Storm Desmond caused extensive and devastating flooding to the village , with torrential rainfall and rivers bursting their banks . Four days later , more rainfall caused rivers to burst their banks once again , leading to even more flood damage to businesses and homes in the village . A ribbon lake is a long and narrow , finger - shaped lake , usually found in a glacial trough . Its formation begins when a glacier moves over an area containing alternate bands ___MASK1___ hard and soft bedrock . The sharp - edged boulders that are picked up by the glacier and carried at the bottom ___MASK1___ the glacier erode the softer rock more quickly by abrasion , thus creating a hollow called a rock basin . On either side ___MASK1___ the rock basin , the more resistant rock is eroded less and these outcrops ___MASK1___ harder rock are known as rock bars , which act as dams between which rainwater may accumulate after the retreat ___MASK1___ the ice age , filling up the rock basin and creating a ribbon lake .
