Power revenues during the calendar year 1966 approached <br />$11 million--a new high for a l2-month period. Cumulative revenues <br />through January 31 of this year reached $22 million. <br /> <br />The sale of surplus energy was discontinued last August when <br />it became apparent that generation for other purposes was sufficient <br />to utilize all the water being released to meet downstream require- <br />ments. Surplus energy deliveries have just recently been started <br />again in limited amounts, which are necessary because of the water <br />that must be released for downstream requirements. <br /> <br />During the past year the Storage Project supplied all the energy <br />deficiency losses at Hoover Dam resulting from the filling of Upper <br />Basin reservoirs. This amounted to more than 900 million kilowatt- <br />hours during the l2-month period ending December 31. It appears that <br />during 1967 we will also be able to replace Hoover deficiencies from <br />storage power generation. <br /> <br />CRSP RESERVOIR OPERATIONS <br /> <br />The water supply picture at this time appears to be favorable. <br />We begin formal forecasting on April to July runoff on January 1 and <br />revise this forecast on the first of each subsequent month through <br />June. As you would expect, these forecasts become progressively more <br />reliable as time passes and more data on precipitation is received. <br /> <br />October and November of 1966 were rather dry, but December proved <br />to be far above 'average so that our January 1 forecast was 118 percent <br />of normal, or 10 million acre-feet at Lees Ferry. The January pre- <br />cipitation was down slightly, reducing our forecast tp 9.9 million <br />acre-feet, or 116 percent of normal. So far Februaryrprecipitation <br />has been far below normal so we can anticipate a substantial reduction <br />in owr April-July forecast on March 1. <br /> <br />Lake Mead <br /> <br />Lake Mead now stands at elevation l,l33. Within the next few <br />months the level of Lake Mead will drop. During the critical bass <br />spawning season, however, the level of Lake Mead should remain rela- <br />tively constant. We expect Lake Mead to reach the l,124-foot minimum <br />elevation this fall. <br /> <br />Lake Powell <br /> <br />Lake Powell should rise above its rated head level, elevation <br />3,570 feet, to 3,574 by July which is about 28 feet higher than the <br />all-time high set last June at elevation 3,546 feet. We are estimating <br />a water year release of 7.9 million acre-feet or about 10 percent: less <br /> <br />4 <br />
