Lake Mead

 is a lake in the Mojave Wasteland.

Layout
It has pure water, so you can drink it and fill up your H2O meter. The area is crawling with lakelurks, so going there to fill up your H2O meter will be no walk in the park.

The lake bed is mostly sand and rocks with the odd bit of seaweed here and there. There are fish in the lake as well. On the lakebed a B-29 airplane can be found, which the Courier is asked to bring up to the surface during the Volare! quest.

There is also an underwater cave in Lake Mead.

Appearances
appears in Fallout: New Vegas.

Lake Mead Cave
The Lake Mead Cave, not to be confused with the Camp Guardian caves, south-east of the Crashed B-29. Directly behind the plane lies a sunken ship, red in color, (which has some Gore bags coming out of a hole in the hull). Directly below that ship lies the cave.

Behind the scenes

 * The crashed B-29 appears to be a reference to an actual airplane crash that happened in the real Lake Mead (http://www.eculturalresources.com/news/756.html).

Bugs

 * There are a few hollow, floating, underwater rocks south-east of the Boulder Beach Campground docks.
 * Just south-east of the hollow, floating, underwater rocks lies an underwater rock face with a "hole" in it big enough for the player to swim in and out thus putting the player inside some rocks.
 * There is yet another "hole" if the shoreline is followed south.
 * When fast traveling to Lake Mead (when you spawn on the boat wreckage), you can often see the crashed B-29, floating off in the distance by the dock. However, when you approach it, it's gone, per the Boomer's quest.
