<br />LAKE HAVASU <br />(COLORADO RIVER) <br /> <br />Water Year 1995 <br /> <br />At the beginning of water year 1995, the water level of Lake <br />Havasu, impounded by Parker Darn, was at an elevation of <br />about 135.2 meters (446.2 feet) with an active storage of <br />approximately 673 million cubic meters (546,000 acre-feet). <br /> <br />During the water year, approximately 8,206 million cubic <br />meters (6,653,000 acre.feet) were released at Parker Darn, <br />all of which passed through the turbines for power <br />production. In addition to the releases from Parker Darn, <br />approximately 1,370 million cubic meters (1,111,tXXl acre- <br />feet) were diverted from Lake Havasu by the Metropolitan <br />Water District of Southern California. Diversions from Lake <br />Havasu for the Central Arizona Project were 875 million <br />cubic meters (709,000 acre-feet) during the water year. <br /> <br />Storage space in the top 3 meters (10 feet) of Lake Havasu <br />which translates into 222 million cubic meters (180,000 acre- <br />feet) is reserved by the United States for control of floods <br />and other uses, including river regulation. <br /> <br />Central ArIzona Project - New Waddell Dam OperaUons <br /> <br />Central Arizona Project (CAP) diversions have steadily <br />increased over the last three years.

From October 1994, to June 1995, an <br />additional 436 million cubic meters (280,500 acre-feet) of <br />water was diverted from the Colorado River and pumped <br />into Lake Pleasant. During a normal year of CAP <br />operation, the planned Lake Pleasant reservoir water <br />elevation will fluctuate between a maximum of 512.1 meters <br />(1,680 feet) and a minimum of 493.8 meters (1,620 feet). <br />The reservoir level will rise, mid-October through May, whiIe <br />Colorado River water is pumped into the Lake. Conversely, <br />the reservoir level will drop, June to mid-October, whiIe <br />water is released into the CAP and Maricopa Water District <br />systems for customer deliveries. <br /> <br />lAKE HAVASU <br /> <br />Reservoir <br /> <br />Slorege Capacity __ ___ 764 million cubic meters (619,400 acre-fect) <br />Normal Pool Elevation 137.2 meteR (450.0 fcet) <br />Minimum Power Pool 134.1 meters (440.0 rect) <br />Surface Area, rull 8.256 hectares (20,400 acres) <br />Reservoir Length, full 57 kilometers (35 miles) <br /> <br />Powerolant <br /> <br />Number of Units <br />TOlal Capacity <br /> <br />4 <br />12ll,000 KW <br /> <br />19 <br />
