That’s enough water to fill the Reflecting Pool on the National Mall about 1,600 times.
As of Monday, Lake Powell was around 25% full, according to data from the Bureau of Reclamation.
The significance of the dwindling water supply along the Colorado cannot be overstated.
The system supplies water for more than 40 million people living across seven Western states and Mexico. Lakes Powell and Mead provide a critical supply of drinking water and irrigation for many across the region, including rural farms, ranches and native communities.
“It is vitally important we have the best-available scientific information like this report to provide a clear understanding of water availability in Lake Powell as we plan for the future,” Tanya Trujillo, assistant secretary for water and science with the US Department of Interior, said in a statement. “The Colorado River system faces multiple challenges, including the effects of a 22-year-long drought and the increased impacts of climate change.”
