Blue Mesa Reservoir - Gunnison County
Ownership: None Listed
Description: This is the largest reservoir in the state and extends eleven miles west from the junction of Highways 50 and 149. During spring and fall migration, up to 24 species of ducks, 25 species of shorebirds, Osprey, Common Loon, and White Pelicans can be seen, along with some interesting gulls (Franklin's, Bonaparte's, and maybe Sabine's or Little). This site is especially good in the fall for Barrow's Goldeneye with as many as 70-100 for about 3 weeks in November and December. Mallards nest here in the summer, but the reservoir is generally frozen over in the winter.

Habitat: Pond/Lake/Reservoir
Directions: US 50 west of Gunnison. The best birding is at the east end.
