Blacks Creek Reservoir is a small reservoir that fluctuates greatly with water supply (drought/rainfall). It is surrounded by sagebrush hills. There are ample mudflats at certain seasons that are used by shorebirds and this site is also used as a migration stop for various waterfowl.

Ornithological Summary

The reservoir is used during the breeding season by multiple species of waterfowl, other waterbirds, and shorebirds. Many shorebirds also use this site during migration, including American Avocet, Black-necked Stilt, Long-billed Dowitcher, Killdeer, and Long-billed Curlew. Burrowing Owls and other raptors can be found along the upland banks of the reservoir.

Conservation Issues

There is significant habitat degradation and bird disturbance resulting from 4WD vehicle use along mudflats. There is also a serious problem with illegal shooting of migratory waterbirds and passerines at this site, as many hunters and shooters use this area for target practice. A shooting closure at the reservoir has been recommended, as availability of enforcement personnel is not sufficient to curb illegal shooting, and future conservation efforts will focus on establishing such a closure. Drought and invasive plants are also threats at the reservoir.


Mostly open water with exposed mudflats when water levels recede. Small riparian corrider of willows and emergent vegetation along southern edge of the reservoir. Reservoir is surrounded by grasslands and sparse sagebrush.
