<br />Glen Cangon <br />Lake Powell <br /> <br />For the current year the level of Lake Powell <br />should drop about 4 feet during the fall and winter <br />months to elevation 3,648 feet with an active <br />storage of 17.6 million acre-feet. Assuming an <br />average April-July 1975 runoff, the resulting <br />inflow of about 8.0 million acre-feet should cause <br />the lake to reach an aU-time high elevation of <br />3,668 feet during July with an active storage of <br />20.1 million acre-feet. This will be about 80 <br />percent of the active capacity of the reservoir. The <br />lake will have a length of 184 miles and a water <br />surface area of 139,510 acres. Total release during <br />water year 1975 of 8.7 million acre-feet is <br />scheduled from Lake Powell, under average <br />conditions, to satisfy storage requirements for <br />Lake Mead and Lake Powell in compliance with <br />Section 602 of Public Law 90-537. The scheduled <br />release will pass through the turbines to genera te <br />power for customers in the Upper Colorado River <br />Basin. (Chart 6) <br /> <br />lower Basin Reservoirs <br /> <br />Lake Mead <br /> <br />The level of Lake Mead during the current <br />year is scheduled to remain essentially level at <br />about elevation 1,174 feet throug'!out wate.!.year <br />1975 . to enhance' the bass spawn and survival <br />conditions. At this level, the lake will have an <br />average active storage of about 19 million acre-feel. <br />A total of 8.5 million acre-feet is scheduled to be <br />released from Lake Mead during water year 1975 <br />to meet all downstream requirements. All releases <br />are scheduled to pass through the turbines for <br />electric power production. (Chart 7) <br /> <br />33 <br />
