Show C. AUTHORIZED STORAGE UNITS (Information relative to Storage Units and participating projects has been obtained from reports on investigations and activities of the United States Bureau of Reclamation, Department of the Interior). The construction of four Storage Units of the Colorado River Storage Project and eleven participating projects was authorized in Section 1 of Public Law 485. The four authorized Storage Units are at Glen Canyon on the Colorado River in Utah and Arizona, Flaming Gorge on the Green River in Wyoming and Utah, Navajo on the San Juan River in New Mexico and Colorado and Curecanti on the Gunnison River in Colorado. Combined they will provide about 34,570,000 acre-feet of reservoir capacity and about 1,108,000 kilowatts of installed generating capacity. 1. Glen Canyon Storage Unit The Glen Canyon Dam and Reservoir will comprise the key Storage Unit and will be the largest of the initial four, providing about 80% of both the storage and generating capacity. It will rise 573 feet above the river and will be roughly comparable in size to Hoover Dam and Lake Mead. The concrete gravity-arch dam located in northern Arizona on the Colorado River, 12.4 miles downstream from the Utah-Arizona state line, and 15.3 miles upstream from Lees Ferry (Lees Ferry is the location of the Geological Survey gaging station and is 1.3 miles upstream from the compact point, Lee Ferry, which divides the Colorado River Drainage into two basins). It will be the second tallest dam in the United States. The reservoir will have a capacity of 28 million acre-feet and will extend 186 miles upstream on the Colorado River, and 71 miles up the San Juan River. The power house, which will be located at the toe of the dam will have eight generating units with a total installed capacity of 900,000 kilowatts. Construction Activities The prime contract for the construction of the Glen Canyon Storage Unit is about 57 per cent complete. Translated into absolute terms, this means that there are 1,700,000 cubic yards of concrete in place in the dam with the highest block about 300 feet above the lowest foundation. Good progress is being made on the construction of the powerhouse also, with 200,000 cubic yards of concrete in place and structural steel being rapidly installed. The contractor is confident that he will be able to meet the schedule for the closing of the gates and initial storage of water in Lake Powell in November, 47 |
