REPORT BY THE BUREAU OF RECLAMATION, REGION 4, TO THE COWRADO WATER CONSERVATION BOAP.D January 14, 1966 Construction The sixth 112,500-kilo~tt generating lL~it in GLEN CANYON POWERPLANT was placed in commercial operation on October 13, bringing the installed capacity of the plant to 675,000 kilowatts.

Two units remain to go on the line to bring the plant to its total installed capacity of 900,000 kilowatts. Unit No.7 is now being tested.

After closure of the diversion tunnel on October 27, storage of water behind Blue Mesa Dam began. The water impounded has already formed a lake 11 Iniles long. The powerplant structure at the toe of the dam is essentially completed. Work remaining under the prime contract includes placement of the downstream plug in the diversion tunnel, work on excava- tion for the channel improvement below the dam, surfacing the highway across the crest of the dam, and modification of the outlet works--most of which is well underway, The upstream plug in the diversion tunnel is in place and completed. Overall completion under the prime contract is about 98 percent.
