San Luis Lakes - Alamosa County
Ownership: None Listed
Description: San Luis Lake State Park, home to the largest body of water in the county, is probably the single best place to find shorebirds and diving ducks in migration, although the Alamosa NWR and the Blanca Wetlands would certainly give it a run for its money (and would beat it handily during the breeding season). A state parks fee is required to view the lake. On the way in, stop to check out the canal, as it can provide close views of diving ducks and/or swallows depending on time of year. The road to the campground provides access to most of the west shore of the lake, but if you want closer views of things to the east, you may have to do some hiking.

Through the state park, past the campground, is the gate to San Luis Lakes State Wildlife Area, where the rest of the San Luis Lakes are. These smaller ponds can be great for waterbirds of all kinds, but they are closed to the public during spring and summer to protect nests.

The entire area of the state park and the state wildlife area is covered with black greasewood and saltbush habitats. Sage Thrasher and Brewer's Sparrow breed throughout.

Habitat: Pond/Lake/Reservoir, Black Greasewood
Directions: From US 160 fourteen miles east of Alamosa and five miles west of Blanca, turn north on CO 150 and proceed 13.5 miles to the intersection with Six Mile Lane (CR 6N). Turn left on Six Mile Lane and head west eight miles to the park entrance on the right. Alternatively, from CO 17 just north of the tiny town of Mosca, head east on Six Mile Lane about eight miles to the park entrance on the left.
