Lake Mead Water Level Map

An interactive 3D map of Lake Mead water levels. It draws the lakebed from the official USGS and Bureau of Reclamation OFR 03-320 survey, reads recorded Bureau of Reclamation water levels, and lets you set any level you like to see which shorelines, basins, and channels would be out of the water. It shows where a chosen water level meets the terrain — it is not a forecast or a hydrological model.

The map itself needs JavaScript and WebGL. These pages do not:
