Yellowstone Lake, WY
Lake in Park County, Wyoming. The largest high-elevation lake in North America at roughly 132 square miles, sitting at 7,733 ft inside Yellowstone National Park. The lake is the heart of the native Yellowstone cutthroat trout's range; the park runs an aggressive lake trout suppression program because illegally introduced lake trout prey on the cutthroat. Anglers fish for both native cutthroat (catch-and-release) and lake trout (mandatory kill). The cold, deep water keeps fishing strongest from the June opener through September. Elevation 7,733 ft.
