Fremont Lake

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.
