The Colorado River helped build southern California and it sustains our economy. It waters our crops and fills our tubs. The river runs from the state of Colorado down to the southeast tip of California and into Mexico. Before the US built massive dams across it, the river roared into Baja and Sonora, Mexico, created vast wetlands, and flowed out to the Gulf of California. Today, it rarely reaches the gulf. But Mexicans are hoping to restore the river and its delta and they're looking to the US for help. KPCC's Ilsa Setziol reports.
