Largest Lakes of Wyoming

Wyoming’s biggest lakes are its great reservoirs — sprawling waters like Flaming Gorge, Boysen, Buffalo Bill, Seminoe, Pathfinder and Glendo, strung along the Green, Wind and North Platte rivers. This is the state’s open water for serious anglers and boaters: concrete launch ramps and full-service marinas, trophy walleye, lake trout, kokanee salmon and cutthroat, and long shorelines for camping, paddling and summer recreation. Many of these lakes anchor a Wyoming state park with developed campgrounds, swim beaches and boat rentals, and most keep producing through winter for ice fishing. Below are in-depth guides to each of Wyoming’s major lakes and reservoirs — surface acres and depth, the fish you’ll catch, boat access, camping options and the best seasons to visit.
