New Waddell Dam and P-G Plant will allow CAP to pump and store Colorado River water in the Phoenix area during the winter months when energy and water demands are low, and then release for delivery in the summer months when energy and water demands are high. The dam and P-G Plant are scheduled to be fully operational in 1995, with initial pump tests and reservoir filling beginning in the fall of 1992. Current construction schedules indicate that operational testing of the pumps will begin in October 1992 and the first pump will be available for commercial operation by November 15, 1992. All eight units are scheduled to be operational by the end of August 1993. Low-speed generator tests will be accomplished through the summer of 1993 when the stored water is released for delivery to CAP customers. In order to facilitate high-speed generator testing required for contract completion, the active conservation storage space in New Waddell Reservoir must be virtually full. To complete this testing before the summer of 1994, the Central Ariwna Water Conservation District must pump at the maximum capacity from the Colorado River beginning in the fall of 1993. Current projections indicate that CAP's use could increase by approximately 400,000 to 500,000 AF as a result filling New Waddell reservoir during calendar year 1993. Senator Wash and Laguna Reservoirs Water conservation operations at Senator Wash Reservoir allow regulation of water deliveries, to Mexico and other irrigation agencies. The reservoir prevents excess flows in the Colorado River below Morelos Dam except during rainstorm or other unusual events. Operational objectives at and below Laguna Dam are to conserve water, control sediment, and maintain the river channel. Storage of water above Laguna Dam in the reservoir, in surcharge, and in bank storage provides for controlled flows in the river at Yuma, which combined with seepage and drainage, allows a continuous live stream serving recreational and fish and wildlife purposes. On a few occasions each year, higher daily flows below Laguna Dam caused by rainstorms or user rejected water orders are used to maintain sufficient river channel capacity. This occasional practice reduces channel maintenance expense without impairment of water conservation or power production. Yuma Desalting Plant Current plans for the Yuma Desalting Plant for fiscal year 1993 are to continue operation of the plant at one-third capacity. Provisions of Minute 242 of the International Boundary and Water Commission will continue to be met by additional releases from storage to compensate for the water bypassed from the Wellton-Mohawk Irrigation District. The water recovered by operating the Yuma Desalting Plant will be used to reduce the additional releases required.
