At <br />that time the lake volume will have dropped to 8.0 million acre-feet from <br />its spring maximum level of about 9.5 million acre-feet. <br />Flaming Gorge Reservoir reached a seasonal maximum elevation of <br />6,010 feet on July 1 and has receded about 4 feet to its present level. <br />During the fall and winter it will be lowered about another 11 feet to <br />elevation 5,995 feet. Total storage of water in Flaming Gorge, now at <br />2.6 million acre-feet, will fall to 2.2 million acre-feet. Releases <br />for recreation purposes were maintained above 1,200 cubic feet per <br />second from the early part of June through Labor Day, but the powerplant <br />is now operating without that restriction. <br /> <br />Navajo Reservoir was held at a low level during the early part of <br /> <br />the summer to permit completion of the diversion tunnel for the Navajo <br /> <br />Indian Irrigation Project. Since the critical part of this work is now <br />complete, the release of water from Navajo Dam has been reduced to about <br /> <br />500 cubic feet per second required for downstream uses. This has increased <br /> <br />storage and enhanced recreational use of the reservoir. The level of the <br /> <br />4 <br />
