Dive Sites in Wyoming, United States

A roughly 2,470-acre reservoir about 30 minutes southwest of Casper on Highway 220, around 100 feet deep, and the most accessible regularly dived site in central Wyoming. The dam area and Sandy Beach generally have the best visibility from June through August. The rocky bottom is stocked with trout, walleye and perch, and freshwater crawfish are common. Best accessed by boat, though some shore entries require only a short walk with gear.

A glacial lake in Grand Teton National Park at about 6,783 feet elevation, one of only two lakes in the park where scuba diving is permitted (the other is Jackson Lake). Divers can descend into an underwater forest of trees deposited by shoreline landslides, reaching down to about 100 feet, with the dramatic Teton range as a backdrop. Boat access from the West Shore Boat Dock area is used to reach the dive zone, and water temperatures around 40F require a drysuit.

The largest body of water in Yellowstone National Park, at about 7,732 feet the largest freshwater lake above 7,000 feet in North America. Guided altitude dives from the shore near Bridge Bay reach 30 to 40 feet, where 20-foot siliceous hydrothermal spires rise from the bottom. Boat access reaches Stevenson Island and the early-1900s E.C. Waters wreck in just a few feet of water, plus dock cribbing near the historic Lake Hotel. Archaeological artifacts are protected and must not be touched, and divers must check in with the Bridge Bay ranger before diving.

A 12-mile-long glacial lake just north of Pinedale in the Wind River Range, and one of the deepest lakes in the country at about 610 feet. It is one of Wyoming's most frequently dived sites, offering certifications and fun dives at 'Swim Beach' (officially Sandy Beach) near the marina, where surface water reaches about 70F before a thermocline at 25-30 feet drops to 40F. Notable areas include Moosehead Bay and Chambers Bay, with car-sized boulders in crystal-clear water; divers also report sunken boats, artifacts and lure-laden underwater trees.
