Flow gages* record discharge in streams and rivers across the U.S. but the extent and adequacy of this monitoring network relative to USFS lands has not been documented. To address that deficiency, the medium resolution National Hydrography Layer was used with gage location information from the National Water Information System to describe the monitoring network and how it has changed through time. Summaries were made for eight USFS regions that describe the number and locations of gages relative to USFS lands and network characteristics such as elevation and watershed area. These summaries are available in the slide show pdfs provided below. To obtain copies of the geospatial datasets used in the summaries contact Charlie Luce (firstname.lastname@example.org; 208-373-4382) or Dona Horan (email@example.com; 208-373-4399).
* NOTE: We use the spelling 'gage' rather than 'gauge', following U.S. Geological Survey standards.
