Willow Creek Dam (Montana)

Willow Creek Dam is a dam in Lewis and Clark County, Montana.

The earthen dam was originally constructed between 1907 and 1911 by the United States Bureau of Reclamation, then modified and reinforced several times since. With a height of 93 ft and 650 ft long at its crest, it impounds Willow Creek for irrigation storage and flood control, part of the Bureau's larger Sun River Project. The dam is owned and operated by the Bureau.

The reservoir it creates, Willow Creek Reservoir, has a water surface of 1530 acre, another 3069 acre of surrounding land, about 11 mi of shoreline, and a maximum capacity of 32400 acre feet. Recreation includes fishing (for rainbow trout and kokanee salmon), camping, hunting, boating, and hiking.
