<br />5442 <br /> <br />acre-feet which is down 1.1 million acre- <br />feet from what is shown in your report. <br /> <br />On the individuals reservoirs, Lake Mead <br />now stands at elevation 1,133, representing 1- <br />a capacity of about 15,600,000 acre-feet. It <br />is anticipated that Lake Mead will be drawn <br />down to about elevation 1,124 feet this fall. <br /> <br />Lake Powell is presently at elevation <br />3,515. We estimate that by July it will <br />raise about 28 feet higher than it has ever <br />risen before. We are estimating a water year <br />release of 7.9 million acre-feet or about <br />10 percent less than the average release we <br />must make from 1967 through 1972 to deliver <br />75 million acre-feet in the decade ending <br />September 30, 1972. We are not alarmed about <br />this delay since estimated increases in firm <br />loads in the next few years should be adequate <br />to meet compact requirement in this critical <br />decade. <br /> <br />The reservoir at Flaming Gorge now con- <br />tains a somewhat greater percentage of its <br />total storage than does Lake powell, so we <br />envision that it will rise seasonally from <br />sno\~lt by July and then recede in about the <br />same pattern which occurred last year. By <br />February 1968, it will be slightly higher <br />than at present. Releases for power will <br />average about 110,000 acre-feet per month. <br />We have a higher proportion of storage in <br />this reservoir than in any of the others. <br /> <br />The lake at Fontenelle Dam is being <br />allowed to rise very slowly, but this will <br />be cut back after April 1 to prepare for <br />repairs to the stilling basin. From April 1 <br />to about August 1 we will pass natural inflow <br />through the river outlets. During the fol- <br />lowing 4-month repair period the natural <br />inflow will be passed through the turbine <br />assembly. After the repairs are completed, <br />we will resume storage and install the tur- <br />bine runner and generator. <br /> <br />1 <br />
