About the Colorado River water crisis
The Colorado River supplies water to roughly 40 million people in seven U.S. states (Arizona, California, Colorado, Nevada, New Mexico, Utah, Wyoming) and Mexico. This dashboard tracks daily Bureau of Reclamation readings for Lake Mead, Lake Powell, and eight other reservoirs.
Since 2000 the basin has been in a drought that tree-ring research rates as the driest stretch in at least 1,200 years. Storage fell to record lows in 2022, triggering mandatory cuts to Arizona, Nevada, and Mexico, and the rules that govern Lake Mead and Lake Powell expire at the end of 2026. Background is on the Southwest water crisis and water shortage pages, with a curated reading list.
