<br />001173 <br /> <br />are available to meet the A WBA' s needs for the next ten years, and the inventory is to be <br />updated at least once every five years. The initial inventory completed in March 1997 <br />with ADWR review found that storage facilities do not exist in the Tucson Active <br />Management Area (AMA) to meet the AWBA's needs. The AWBA found that storage <br />facilities exist in the Phoenix and Pinal AMAs to meet their needs. The AWBA found <br />that no storage facilities are necessary to meet their needs in areas of the State outside the <br />Phoenix, Pinal and Tucson AMAs. There are no storage facilities currently existing <br />Dutside the Phoenix, Pinal and Tucson AMAs capable of physically receiving and storing <br />CAP water. The Storage Facilities Inventory (Appendix B) provides a listing of existing <br />storage facilities sufficient to meet A WBA needs in Arizona (A WBA 1997); <br /> <br />I <br />I <br />f. <br /> <br />. <br /> <br />The AWBA has indicated that water stored pursuant to interstate banking agreements <br />would be stored in existing State permitted facilities in which they have contracted <br />storage space. The Consuming State entity will be required to pay for the delivery and <br />storage of the water and could then recover credits attributable to 95% of the stored <br />water; <br /> <br />. <br /> <br />Nevada has limited off stream storage capacity. The Las Vegas Valley Water District <br />began recharging Colorado River water in the Southern Nevada Groundwater Bank in <br />1987. Through 1996, approximately 1l0,000 afhad been recharged, with plans to <br />recharge at least a total of350,000 af This water is used to meet the Southern Nevada <br />Water Authority purveyor's demands including summer peaking, Studies continue on <br />ground water recharge. Nevada has not identified any storage facilities that would be <br />used in interstate transactions and is unlikely to develop any for this purpose, Nevada <br />most likely would be a consuming State. At present, Nevada entities have not developed <br />provisions related to interstate transactions; <br /> <br />l <br /> <br /> <br />I <br /> <br />I <br /> <br />. In California, the Desert Water Agency (Desert) and the Coachella Valley Water District <br />(CVWD) entered into agreements with MWD to recharge the groundwater basin of the <br />upper Coachella valley with Colorado River water. Under those agreements, MWD <br />exchanges Colorado River water for water available to Desert and CVWD from the <br />California State Water Project under those agencies' water delivery contracts with the <br />State of California. Those groundwater storage sites have the potential for use to store <br />water for interstate transactions, It is unknown if California entities will develop any <br />off stream storage facilities for use in interstate transactions. This analysis assumes that <br />California will be a consuming State; and <br /> <br />. MWD also has a program that involves contracting with its member agencies for <br />groundwater recovery, MWD's 1995 annual report lists the following projects; six <br />projects under contract with a projected ultimate yield Df 18,039 afper year, three <br />projects under negotiation (at that time) with a projected ultimate yield of29,915 afper <br />year, and five additional projects under review with a projected ultimate yield of <br />33,800 afper year. Together, these groundwater recovery projects would yield 81,754 af <br />per year for MWD's use after full development of the required recharge/recovery <br /> <br />LC Region DEAl I <br /> <br />7 <br /> <br />12/97 <br /> <br />
