Site details

Montana's third-largest body of water, a Missouri River reservoir downstream of the Three Forks confluence, completed in 1954. Three marina concessions (Goose Bay, Kim's, and Yacht Basin) provide services, and local divers use the reservoir for fun dives, though clarity is limited and not ideal for new-diver open-water training. The rocky and silty bottom holds abundant warm-water and cold-water fish.
