Lake Mead Water Levels — Historical and Current

This chart is dynamically updated. This page reads data from a government archive of water heights for Lake Mead from 1935 to the present, and draws the chart on that basis. The database, located at http://www.usbr.gov/lc/region/g4000/hourly/mead-elv.html, is updated once per month.

This page's graphic updates itself in step with the data source, over time giving an easy-to-interpret picture of Lake Mead water levels.
