About the Colorado River Water Crisis

The Colorado River supplies water to approximately 40 million people across seven U.S. states (Arizona, California, Colorado, Nevada, New Mexico, Utah, Wyoming) and Mexico. Our dashboard tracks daily Bureau of Reclamation readings for Lake Mead water levels, Lake Powell capacity, and 8 other critical reservoirs.

Since 2000, the region has experienced a megadrought - the worst in over 1,200 years. This Southwest water crisis has pushed reservoir levels to historic lows, triggering mandatory water cuts to Arizona, Nevada, and Mexico. Stay informed with our water shortage updates and Colorado River news.
