The NPS administers the recreational facilities. In 1994 there were 1,064,538 visitors (latest available figures). 5. Storage Units Fishery Information The Flaming Gorge, Wayne N. Aspinall, Glen Canyon and Navajo Units continue to provide excellent warm- and cold-water fishing both in the reser- voirs and in the tailwater streams below the dams. Use on the reservoirs currently totals approximately 946,000 angler days each year. Lake Powell provides approximately half of the total use, with the remainder coming from the other reservoirs. Lake Powell is almost exclusively a warm-water fishery with striped bass, crappie, walleye, channel catfish and smallmouth and largemouth bass as the harvested species. Angling use on reservoirs appears to be constant, while demand and use for the tail waters is increasing dramati- cally. Navajo and Flaming Gorge Reservoirs provide both warm-water and cold- water fishing, with rainbow trout and kokanee the predominant cold-water harvest and catfish, bass and crappie (at Navajo only) the preferred warm- water fishes. Flaming Gorge also provides a world-class lake trout fishery. The Aspinall reservoirs are exclusively cold-water fisheries, with kokanee and rainbow trout the predominant catch. The four tailwaters (the San Juan River below Navajo Dam, the Green River below Flaming Gorge Dam, the Gunnison River below Crystal Dam and the Colorado River below Glen Canyon Dam) have provided "blue ribbon" trout fishing that many view as some of the best in the western United States. Combined, the annual use of these tailwaters is approximately 500,000 angler days. The Green River (below Flaming Gorge Dam) receives about half of the total use with the Colorado River (below Glen Canyon Dam), the San Juan River (below Navajo Dam) and the Gunnison River (below Crystal Dam) providing the remainder. The net economic value of angling from Glen Canyon Dam to Lees Ferry has been estimated at $1.2 million. B. TRANSMISSION DIVISION The power system includes high voltage transmission lines that intercon- nect to the CRSP hydro-powerplants and deliver power to major load centers or to other delivery points. The system is interconnected with adjacent Federal, public and private utility transmission systems. The Transmission Division was transferred to Western, Department of Energy, in fiscal Afear 1978. 42
