Arizona Water Banking Authority (“AWBA”)

A 3rd REVISION for the next meeting of _______ included this item on the Meeting Agenda Arizona Water Banking Authority (“AWBA”)

The Arizona Water Banking Authority (AWBA; Water Bank) was established in 1996 to store the unused portion of Arizona's annual Colorado River entitlement in Central and Southern Arizona.

The AWBA stores water in underground aquifers to earn long-term storage credits. These credits can be recovered (pumped) during a shortage to provide back-up water supplies (known as "firming") for Arizona water users.

Through 2020, the Water Bank has accrued 4.36 million acre-feet (MAF) of long-term storage credits (LTSCs):

3.75 MAF for Arizona uses and

613 KAF on behalf of the State of Nevada.

The AWBA firms water supplies for Central Arizona Project (CAP) Municipal and Industrial (M&I) subcontract holders and communities along the Colorado River.

As the agent for the State, the AWBA is responsible for meeting the State's Indian firming obligations under the Arizona Water Settlements Act (AWSA).

The Water Bank also assists with meeting the State's water management objectives under the Groundwater Code and provides the mechanism for interstate water banking with the other Lower Basin States.

By storing water, the Water Bank helps to ensure long-term water supplies for Arizona and neighboring states.

2022 Tier One Shortage

The U.S. Secretary of the Interior has declared the first-ever Tier 1 shortage for Colorado River operations in 2022.

This Tier 1 shortage will result in a substantial cut to Arizona’s share of the Colorado River – about 30% of Central Arizona Project’s normal supply; nearly 18% of Arizona’s total Colorado River supply.
