Accessible Ish Reservoir - Boulder County
Ownership: None Listed
Description: This is a good-sized, shallow reservoir owned by a hunting club and closed to the public, but easily scannable from the road. It can be great for waterbirds. If water levels are low, shorebirds can be numerous. Sometimes the lake dries up, creating winter longspur habitat.

Habitat: Pond/Lake/Reservoir
Directions: From Longmont, head three miles north on US 287 and turn right (east) on CR 2 (Yellowstone Road). Proceed one mile to 115th Avenue and turn left. Half a mile north, 115th skirts the eastern edge of the reservoir. Pull as far over as possible and scan from the road. Note that a small slice of the lake at its north end is in Larimer County.
