Fallout: New Vegas locations project
Lake Las Vegas
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.
