LAKE HAVASU (COLORADO RIVER) Water Year 1993 At the beginning of water year 1993, the water level of Lake Havasu, impounded by Parker Dam, was at an elevation of about 136.1 meters (446.4 feet) with an active storage of approximately 678 million cubic meters (550,000 acre-feet). During the water year, approximately 6,929 million cubic meters (5,618,00) acre-feet) were released at Parker Dam, all of which passed through the turbines for power pr.oduction. In addition to the releases from Parker Dam, approximately 1,491 million cubic meters (1,209,000 acre- feet) were diverted from Lake Havasu by the Metropolitan Water District of Southern California. Diversions from Lake Havasu for the Central Arizona Project were 1,085 million cubic meters (880,000 acre-feet) during the water year. Storage space in the top 3 meters (10 feet) of Lake Havasu which translates into 222 million cubic meters (180,000 acre- feet) is reserved by the United States for control of floods and other uses, including river regulation. Central Arizona Projed . New Waddell Dam Operatioo. A key feature of the Central Arizona Project (CAP) is New Waddell Dam and Reservoir.

Colorado River water will be pumped into and released from the reservoir via the Waddell Pumping-Generating Plant (P- G Plant). New Waddell Dam and P-G Plant will allow most of CAP's Colorado River water entitlement to be pumped into the Phoenix area and stored during the winter months when energy and water demands are low, and then released 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, but initial pump tests and reservoir filling began in the fall of 1992. Pump and generator testing continued through 1993, with the goal of completing all testing before the summer of 1994. CA WCD anticipates pumping a total of about 160 million cubic meters (130,000 acre-feet) of Colorado River water into New Waddell Reservoir between January 1, and March 31, 1994. This will result in a full reservoir available for completion of all testing by May 15, 1994. Begirining in October 1994, Colorado River water will be pumped through the CAP system and stored in New Waddell Reservoir for use during the summer of 1995. Total 1994 CAP diversions from the Colorado River are not expected to exceed m million cubic meters (630,000 acre-feet). LAKE HAVASU Reservoir Storage Capacity Nonna!
