Lake Las Vegas is a location in the Mojave Wasteland in 2281. It is adjacent to Camp Golf, a New California Republic camp. It is separate from Lake Mead, with a small dam in the northeast edge of the lake.
Dammed at its northeastern end by the NCR, who have a sizable presence at the adjacent Camp Golf, this provides a good source of water for the NCR sharecropper farms to the northwest, thanks to the snaking pipeline.
There are some remains of golf and shopping carts, and plenty of tires scattered across the lake bed. There's also a drainage pipe on the northeastern side and a Sunset Sarsaparilla crate on a cliff face to the southwest of the lake next to a green yard chair.
Lake Las Vegas appears only in Fallout: New Vegas.
Behind the scenes
Lake Las Vegas is located in the same geographical area as the real world Lake Las Vegas, a man-made lake featuring several resorts and golf courses along its perimeter.
