AWBA Activities



AWBA staff meet annually with permitted recharge facility operators and Central Arizona Project (CAP) staff in developing the Annual Plan of Operation that governs the operations of the AWBA over the course of the calendar year. Further information on current funding sources and projected recharge activity can be obtained from the most recently published Annual Plan of Operation. In July, the AWBA publishes an Annual Report that shows accounting for the previous calendar year.

Arizona’s annual allocation of Colorado River water is 2.8 million acre-feet (MAF).  Total consumptive use of Colorado River water by Arizona for 2016 was approximately 2.6 million acre-feet. Of that, approximately 1.06 million acre-feet were used directly along the Colorado River, and 1.41 million acre-feet were used by CAP. The AWBA recharged 65,708 acre-feet of CAP water in 2016, all of which was for Arizona uses.  No water was recharged on behalf of Nevada.  Since its inception in 1996, approximately 4.1 million acre-feet of water has been delivered for AWBA storage.

The volume of Excess CAP water available to the AWBA has been decreasing since 2010.  In 2016, only 65,708 acre-feet was available for storage by the AWBA.  Recent modeling of Colorado River hydrologic conditions conducted by the USBOR, the ADWR and the CAWCD indicate that shortage conditions could be realized as early as 2019.  Should such a shortage condition occur, it is not expected to affect those who benefit from AWBA storage at this juncture.  Although, no Excess CAP water would be available for water banking purposes.

Through 2016, the AWBA will have accrued over 4.1 million acre-feet of credits at a cost of just over $368 million.  Of this total volume, intrastate credits totaled 3.5 million acre-feet at a cost of $258 million or $74 per acre-foot and interstate credits totaled 551,041 acre-feet at a cost of just under $110 million or $198 per acre-foot.  In addition to the credits accrued by the AWBA, 50,000 acre-feet of credits previously accrued by CAWCD were transferred to the account creating a total of 601,041 acre-feet of credits available for Nevada.  Through 2015, the AWBA expended $8 million in shortage reparation monies and has accrued 109,489 acre-feet in credits.
