The Arizona Water Banking Authority was created in 1996 to store the unused portion of Arizona’s annual allocation of the Colorado River. By storing this unused water the AWBA secures a dependable water supply necessary to ensure the state’s long-term prosperity. The plan is intended to govern the operations of the AWBA over the course of the entire calendar year.

The Arizona Water Banking Authority was created in 1996 to store the unused portion of Arizona’s annual allocation of Colorado River water. Until the AWBA was created, Arizona had not fully utilized its 2.8 million acre-foot allocation of Colorado River water and the state’s leaders recognized that leaving a portion of Arizona’s allocation in the river was a lost opportunity. The AWBA was created to provide assurances that water users within the state had secure, long-term water supplies.
