Clark Canyon Dam is constructed at the head of the Beaverhead River. Clark Canyon Reservoir is the site of Camp Fortunate, one of the more significant spots along the Lewis and Clark Trail. It was at Camp Fortunate that the Lewis and Clark expedition met the Lemhi Shoshoni Tribe, and cached their canoes and a stash of supplies for the return trip. Sacagawea was reunited with her people here.
