Beulah Reservoir is nestled in Agency Valley on the North Fork of the Malheur River in Oregon, almost filling the small triangular valley. There are campgrounds and facilities for launching and mooring boats at the reservoir. A wide variety of migrating waterfowl use the reservoir, with heavy use by Canada geese. Mule deer and elk are also present in the area. The reservoir is 1,900 acres with Dolly Varden, rainbow, and cutthroat trout. Agency Valley Dam and Beulah Reservoir are features of the Vale Project.
