Toggle Image Quantification Settlement Agreement (QSA) Fact Sheet 02/23/2005 (PDF, 69 KB)
Description: The Colorado River is the source of much of Southern California’s water supply. It has been allocated among western states through a series of laws, court decisions and agreements dating back to the 1920s. Until recently, Arizona and Nevada did not use their full share of Colorado River water, and California was allowed to use water that was not used by these states. Due to growth in these other states, California has been required to reduce its use of Colorado River water to its basic allocation.
