A watershed is the land area that drains water to a particular stream, river, or lake. It is a land feature with boundaries that can be identified by tracing a line along the highest elevations between 2 drainage areas on a map, often a ridge. Large watersheds, like the Mississippi River basin, contain thousands of smaller watersheds. The Ruedi Reservoir, Frying Pan River and Crystal River watersheds are part of the Roaring Fork Watershed.
