Show miles up the San Juan River. The powerhouse, which is located at the toe of the dam, will have eight generating units with a total installed capacity of 900,000 kilowatts. Construction Activities On September 13, 1963, the last bucket of mass concrete was placed in Glen Canyon Dam, bringing all blocks in the massive structure to their final 710-foot height. Nearly 5,000,000 cubic yards of concrete went into the dam. Storage of water began in Lake Powell behind the dam on March 13, 1963. By September 30, 1963, the lake had backed up 130 miles, was 250 feet deep near the dam, and contained 2,535,000 acre-feet of water. Another 3,600,000 acre-feet of water are required to reach the minimum power pool of 6.1 million acre-feet at elevation 3490 feet above sea level. Turbines and generators are being installed in the powerhouse at the foot of the dam, with the first power due to be generated in the autumn of 1964. 2. Flaming Gorge Storage Unit Flaming Gorge Dam is located on the Green River in northeastern Utah, about 40 road miles north of Vernal, Utah, and 32 river miles downstream from the Utah-Wyoming state line. The dam is a concrete thin-arch structure rising 502 feet above the riverbed. The reservoir will have a capacity of 3,789,000 acre-feet and will extend upstream 94 miles, nearly to the town of Green River, Wyoming. The powerplant will have an installed generating capacity of 108,000 kilowatts. Construction Activities Flaming Gorge Dam is now essentially completed and the first Colorado River Storage Project hydroelectric power has gone on the line from the Flaming Gorge Powerplant. Flaming Gorge Dam was finished on November 15, 1962. By the end of the water year the completion contractor had finished about 85 percent of the work of installing the generators and turbines in the powerhouse. On November 1, just two weeks before the dam was completed, the stop logs were dropped into place at the diversion tunnel inlet, and storage of water in Flaming Gorge Reservoir began. Storage at Flaming Gorge reached the minimum power operating level on June 1, 1963, and the reservoir level continued to rise. On September 27, 1963, President John F. Kennedy gave the signal to start the test runs for generating unit No. 1. By November 11th all the tests had been completed and generating unit No. 1 went on the line. 45 |
