The Colorado River system provides about 35 million Americans with a portion of their water supply. It irrigates 5½ million acres of land in the West and provides water to tribes, parks, and wildlife. The system serves parts of seven States and Mexico—but reservoir levels have crept lower over the past several years, sparking questions about how much water remains and who will have access.
The water in the Delta arrives primarily from the Sacramento and San Joaquin Rivers, supplying water for more than 22 million people. This water source supports California’s trillion-dollar economy—the sixth largest in the world—and its $27 billion agricultural industry.

Atmospheric rivers are a global weather phenomenon that can bring large amounts of rain or snow to the U.S. West Coast each year. These rivers of wet air form over the Pacific Ocean near Hawaiʻi and pick up large amounts of moisture from the tropics and on their way to the West Coast. This moisture is carried in narrow bands across the Pacific Ocean to California, Oregon, Washington and Nevada.
When wildfires spread and scorch the earth, people like Penny Luehring have to act fast. Secondary impacts such as debris flows can be devastating to nearby communities.
