Hungry Horse Dam

Hungry Horse Dam is on the South Fork of the Flathead River, 15 miles south of the west entrance to Glacier National Park and 20 miles northeast of Kalispell, Mont.

The dam site is a deep, narrow canyon about five miles southeast of the South Fork's confluence with the main Flathead River. The Hungry Horse Project is in the Flathead National Forest, Flathead County, Mont.

The project includes the dam and appurtenant works, reservoir, powerplant, switchyard, visitor center, and viewpoint shelter overlook. At the time of its completion, the dam was the third largest dam and the second highest concrete dam in the world.

Hungry Horse plays an important role in flood control and recreation for Flathead County, as well as meeting the growing power needs in the Pacific Northwest.

Effective July 28, 2021, masks are now required for all employees, onsite contractors and visitors inside agency workspaces and federal buildings — regardless of vaccination status if the facility is within an area that has substantial or high COVID community transmission. These safety protocols are consistent with the Centers of Disease Control and Prevention updated guidance.
