Show CHAPTER III 75 D.2 Storage Projects Curecanti Unit The Curecanti Unit develops storage and power possibilities along a 40-mile stretch of a deep canyon section of the Gunnison River above the Black Canyon of the Gunnison National Monument and below the town of Gunnison, Colorado. The facilities include three dams and reservoirs with powerplants. The developments, in order moving downstream, are Blue Mesa, Morrow Point, and Crystal. The Blue Mesa Dam, Reservoir, and Powerplant are constructed. Initial power was produced September 1967. The reservoir's total capacity is 941,000 acre-feet. The powerplant contains two 30,000 kW generators. Morrow Point Dam and Reservoir, about 11 miles downriver from Blue Mesa Dam, is complete. The total storage capacity of the reservoir is 117,000 acre-feet. The powerplant contains two 60,000 kW generators. Crystal Dam and Reservoir, about 8 miles below Morrow Point Dam, is complete. The capacity of the reservoir is 27,240 acre-feet. The powerplant will house a single 28,000 kW generator and is under construction. Flaming Gorge Unit Flaming Gorge Dam is on the Green River, a major tributary of the Colorado River, in northeastern Utah about 20 miles west and 6 miles south of the corner common to Utah, Wyoming, and Colorado. The dam is a concrete, thin arch structure, 502 feet high and 1,285 feet long and was completed in 1963. The reservoir has a total storage capacity of 3,789,000 acre-feet. The powerplant contains three 36,000 kW generators, the last one installed February 1964. Initial power was produced November 1963. Glen Canyon Unit Glen Canyon Dam is on the Colorado River in northern Arizona, about 13 river miles upstream from Lees Ferry and was completed in 1964. It is the only one of the authorized dams on the mainstream of the Colorado River. Glen Canyon Dam is a gravity arch concrete structure, 710 feet high and 1,560 feet long. The dam is one of the highest in the world and, of the Federally constructed dams, is second in height only to Hoover Dam in the United States (Oroville Dam in California is higher). The reservoir has a maximum capacity of 27,000 acre-feet. When full, it will cover about 163,000 acres and extend 186 miles up the Colorado River, nearly to the mouth of Green River, and 71 miles upstream on the tributary San Juan River. About 1,998,000 acre-feet of reservoir capacity is inactive and is useful for sediment accumulation, protection of fish, and helps provide the power head at the dam whose minimum power pool is 6,124,000 acre-feet of water. A powerplant and a switchyard have been constructed at the dam. The powerplant includes eight generating units with a total installed capacity of 950,000 kW. Storage of water in the reservoir was initiated January 23, 1963. Initial power was produced September 1964. The last generator was installed in February 1966. Nauajo Unit Navajo Dam is on the San Juan River in New Mexico about 35 miles east of Farmington and was completed in 1963. The Navajo Reservoir has a total capacity of 1,709,000 acre-feet, of which about 12,600 acre-feet are inactive. Transmission Division The authorizing Act of April 11, 1956, provides that project powerplants and transmission facilities shall be operated in conjunction with other Federal powerplants, present and potential, so as to produce the greatest |
