<br />0262 <br /> <br />PRESIDENT'S REPORT <br /> <br />TO THE STOCKHOLDERS OF <br />THE TWIN LAKES RESERVOIR AND CANAL COMPANY <br /> <br />Gentlemen: <br /> <br />The 1971~1972 season's snow pack on our transmountain watershed was <br />below normal. The snow survey taken April 28, 1972, showed the water <br />content on the western slope to be 92% of normal. <br /> <br />From November 1, 1971 to November 1, 1972, we brought 44,669 acre feet <br />of water through Tunnel No. 1 according to the water commissioner's <br />computations of the East Portal measurement charts. The tunnel was shut <br />off from October 10, 1971 to March 22, 1972 to complete the concrete <br />lining. The maximum discharge through the tunnel was 610 eubic feet per <br />second at 6:00 A.M. on June 6, 1972. <br /> <br />Prior to completion of the tunnel lining the maximum discharge in recent <br />years had been 476 cubic feet per second. For 16 days in May and June <br />the tunnel discharge exceeded this amount rendering 3,430 acre feet of <br />additional water. Some spilling still occurred due to the rate of snow <br />melt being greater at times than the oapaoity of the tunnel. <br /> <br />Following is a tabulation in aore feet of the Independenoe Pass Trans_ <br />mountain Diversion System's water produotion for the past five years: <br /> <br />~ <br /> <br />1972 <br />1971 <br />1970 <br />1969 <br />1968 <br /> <br />PRODUCTION <br /> <br />Total <br />S Year Average <br /> <br />44,669 <br />;0,493 <br />61,160 <br />;0,777 <br />;0.017 <br />2;7,116 <br />;1,423 <br /> <br />The ooncrete lining of Tunnel No.1 and the oonstruotion of a nell 12 foot <br />Parshall flume and recorder house at East Portal lIere oompleted bT The <br />Eagle Construotion Corporation in lIIid Maroh, 1972.

The first we.ter for irrigation was released from <br />Twin Lakes Reservoir on April 6, 1972 at whioh time storage was 31,;00 <br />aore feet. The greatest amount in storage during 1972 was 41,362 acre <br />feet on July 4th. As of January ;, 1973, Twin Lakes Reservoir contains <br />24,000 acre feet. <br /> <br />-1- <br />
