De Weese Reservoir - Custer County
Ownership: None Listed
Description: The largest reservoir in Custer County is often quite productive, and is an essential stop for any Custer County lister. The lake itself often holds large rafts of ducks, and when low can have good mudlflats that have attracted many shorebirds. Gulls and terns can sometimes be seen in small numbers. The grassy bluffs around the lake can often produce good-sized flocks of sparrows. Keep an eye out for hummingbird feeders on the small cabins on the way to the lake, and for sparrows and hawks on the road between De Weese and Westcliffe. The best scanning points for the lake are from the bluff on the SE side, from a similar bluff on the NE side, and from the boat ramps on the north side.

Habitat: Reservoir, Grassland/Prairie
Directions: From the center of Westcliffe, drive north on CO 69 for less than half a mile and take a right onto Lake De Weese Rd (CR 241). Travel north for 4 miles and bear left when CR 241 goes right to the boat ramp. Follow this road to the fifth right (Elk Lane), and take a right. Go to the end of the road to a bluff overlooking the lake. This is the best place from which to scan the southern half of the lake. The northern half of the lake is best scanned from the boat ramp reached by going right at the fork described above rather than left.
