Naknek Lake is a lake in southern Alaska, near the base of the Alaska Peninsula. Located in Katmai National Park and Preserve, the lake is 40 miles (64 km) long and three to eight miles (4.8 to 12.9 km) wide, the largest lake in the park. The lake drains west into Bristol Bay through the Naknek River.[1] The elevation of the lake has lowered over the past 5,000 years as it has cut through a glacial moraine, separating Naknek Lake and Brooks Lake and creating Brooks Falls about 3500 years ago.[2]
The earliest Russian explorer reported the lake's name as Naknek, but a later one said its name was "Akulogak". Ivan Petrof named the lake Lake Walker, for Francis Amasa Walker, Superintendent of the 1880 United States census.
The lake is famous for its sport fishing, supporting one of the largest king salmon fisheries in southwestern Alaska, though the king salmon are greatly outnumbered by sockeye salmon as well as pink and chum salmon. Large rainbow trout are also common around the lake, along with northern pike, lake trout and Arctic char. Brooks Camp is located on the lake's shore where the Brooks River enters the lake over rapids.[3]
