The Colorado River — a vital water source for 40 million people in the Southwest — is seriously imperiled by overallocation and the effects of climate change. The need to swiftly reform the use of Colorado River water is clear. That’s why NRDC (Natural Resources Defense Council) along with a coalition of Waterkeepers and other local advocacy groups are asking the U.S. Bureau of Reclamation to utilize its legal authority to stop the waste of Colorado River water in Lower Basin states, including California.
