Lake Mead Water Level Map

An interactive 3D map of Lake Mead water levels. It draws the reservoir floor from the official USGS and Bureau of Reclamation OFR 03-320 integrated terrain, reads recorded USBR pool elevations, and lets you set a hypothetical elevation to see which shoreline, basin, and channel features would be exposed. It is an elevation-intersection visualisation, not a hydrodynamic model or a forecast.

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