Camping at Blackfoot Reservoir Campground near Soda Springs

Blackfoot Reservoir stretches across as much as 18,000 surface acres when full, making it the second-largest reservoir in southeastern Idaho; its design maximum water surface elevation is 6,124 feet, with the main dam standing 55 feet above the streambed and storing about 413,000 acre-feet of usable water. The reservoir's primary purpose is irrigation for lands on the Fort Hall Indian Reservation and surrounding farms, and that management split shows on the ground: the Bureau of Indian Affairs oversees the reservoir while the Bureau of Land Management operates the Blackfoot Reservoir Campground and five nearby campgrounds along the Blackfoot River.
