of the Kern Fan Project, are kept in storage and may be used during periods of shortage to further supply reliable sources of water to IRWD customers. Through the Water Banking Program facilities and agreements, IRWD has 135,500 AF of available storage capacity. This includes 126,000 AF in the existing IRWD Water Bank plus an additional 9,500 AF in the Kern Water Bank. IRWD has 44,600 AF of recharge capacity and 28,750 AF of recovery capacity in the existing IRWD Water Bank. IRWD has an additional 25,000 AF of storage capacity, 15,000 AF of recharge capacity and 7,200 AF of recovery capacity in the initial Kern Fan Project facilities. The Kern Fan Project is being developed and implemented as a joint venture between IRWD and Rosedale-Rio Bravo Water Storage District through the Groundwater Banking Joint Powers Authority. As previously described, IRWD has entered into a Coordinated Operating Agreement (COA) with Metropolitan and MWDOC which allows IRWD to have SWP water recovered from the Water Bank and delivered to IRWD’s service area. Metropolitan intends to amend the COA in 2026 to include the Kern Fan Project facilities. In 2014, IRWD and Metropolitan entered into an agreement for transferring non-SWP water into IRWD’s service area. Under this agreement, in 2015, IRWD recovered and delivered 1,000 AF of its non-SWP water to its service area. This was used July 1, 2015 through February 2016 as extraordinary supply to supplement reduced imported supplies during a water supply allocation from Metropolitan during the drought. IRWD staff continuously tracks available water for emergency supplies with accounting databases for water banking operations, water supply deliveries, and facility operations. C. Reporting The AWSDA is to be completed and submitted to DWR prior to July 1 each year.
