  • Operation of Flaming Gorge Dam Final Environmental Impact Statement
    Record of Decision Operation of Flaming Gorge Dam Final Environmental Impact Statement I. Summary of Action and Background The Bureau of Reclamation (Reclamation) has completed a final environmental impact statement (EIS) on the operation of Flaming Gorge Dam. The EIS describes the potential effects of modifying the operation of Flaming Gorge Dam to assist in the recovery of four endangered fish, and their critical habitat, downstream from the dam. The four endangered fish species are Colorado pikeminnow (Ptychocheilus lucius), humpback chub (Gila cypha), razorback sucker (Xyrauchen texanus), and bonytail (Gila elegans). Reclamation would implement the proposed action by modifying the operations of Flaming Gorge Dam, to the extent possible, to achieve the flows and temperatures recommended by participants of the Upper Colorado River Endangered Fish Recovery Program (Recovery Program). Reclamation’s goal is to implement the proposed action and, at the same time, maintain and continue all authorized purposes of the Colorado River Storage Project. The purpose of the proposed action is to operate Flaming Gorge Dam to protect and assist in recovery of the populations and designated critical habitat of the four endangered fishes, while maintaining all authorized purposes of the Flaming Gorge Unit of the Colorado River Storage Project (CRSP), including those related to the development of water resources in accordance with the Colorado River Compact. As the Federal agency responsible for the operation of Flaming Gorge Dam, Reclamation was the lead agency in preparing the EIS. Eight cooperating agencies also participated in preparing this EIS: the Bureau of Indian Affairs (BIA), Bureau of Land Management, National Park Service, State of Utah Department of Natural Resources, U.S.

  • The Impact of the Endangered Species Act on Glen Canyon Dam Operations and Stakeholders
    The Bottom Line: The Impact of the Endangered Species Act on Glen Canyon Dam Operations and Stakeholders By Leslie James he Endangered Species Act (ESA) is arguably the most powerful environmental law ever enacted. Since its passage in 1973, it has had far-reaching Timpacts on power production from federally owned multiple-purpose projects, such as the Colorado River Storage Project (CRSP). Operational changes resulting from efforts to address ESA issues impact not only power production but repayment of the federal investment in the project. While differing approaches and programs have been established in an attempt to address ESA issues at Glen Canyon Dam, operations have proved to be significant and costly. Background: Colorado River Storage Project In 1956, Congress passed the Colorado River Storage Glen Canyon Dam. Project Act to provide storage facilities for the Upper Basin states so that they could meet Colorado River Compact needs. Operated by the Bureau of Reclamation, the CRSP of total CRSP generation. Flaming Gorge Dam is on the consists of multipurpose dams that release water to meet Green River, a major tributary of the Colorado River, and Colorado River Compact, municipal and industrial (M&I), has three units producing about 132 MW of generation. and irrigation requirements. As the water is released, electric power and energy are produced to help pay for ESA Impacts on Glen Canyon Dam Operations the projects. The Western Area Power Administration The Glen Canyon Dam power plant generates power (WAPA) markets and transmits that electricity to for municipal, industrial, irrigation pumping, and other preference power entities pursuant to federal law.

    River Flow Advisory Bureau . of Reclamation Upper Colorado Region Salt Lake City, Utah Vol. 15, No. 1 September 1984 River flows in the Upper Colorado River drainage, still high for this time of year, are not expected to decrease much for several weeks: While the daily update of operations and releases has been discontinued, the toll-free numbers now provide updates on Bureau of Reclamation activities and projects. Utah residents may call 1-800-624-1094 and out-of-Utah residents may call 1-800-624-5099. Colorado River at Westwater Canyon The flow of the Colorado River on September 10 was 7, 000 cfs, and is expected to decrease slightly over the next few weeks. Cataract Canyon Includin2 the Green- River The flow was 11,500 cfs on September 10 and will continue to decrease slightly. Lake Powell Lake Powell's elevation on September 10 was 3,699. Assuming normal inflow for this time of year, the lake should continue to go down slowly to elevation 3,682 by next spring. Colorado River through Grand Canyon . Releases through Glen Canyon Dam remain at 25,000 cfs. These releases are expected to be maintained with no daily fluctuations in river flows. Upper Green River - Fontenelle Reservoir Fontenelle Reservoir is now at elevation 6,482 feet. Releases through the dam will be reduced to about 600 cfs starting on September 17 for about 2 weeks during powerplant maintenance. Green River Flows Below Flaming Gorge Dam On September 10 Flaming Gorge Reservoir was at elevation 6,039.9 feet. Releases from the dam are expected to average 2, 500 cfs in September and October with usual daily fluctuations.

On January 30, 1978, a reorganization within the U.S. Department of the Interior resulted in BOR being restructured and renamed the Heritage Conservation and Recreation Service (HCRS). On March 27, 1978, study responsibility was transferred from HCRS to the National Park Service. The draft environmental statement was prepared by HCRS and cleared by the U.S. Department of the Interior prior to March 27, 1978. Final revisions and publication of both the draft environmental statement, as well as this document have been the responstbility of the National Park Service.

    Management of the Colorado River: Water Allocations, Drought, and the Federal Role Updated March 21, 2019 Congressional Research Service https://crsreports.congress.gov R45546 SUMMARY R45546 Management of the Colorado River: Water March 21, 2019 Allocation, Drought, and the Federal Role Charles V. Stern The Colorado River Basin covers more than 246,000 square miles in seven U.S. states Specialist in Natural (Wyoming, Colorado, Utah, New Mexico, Arizona, Nevada, and California) and Resources Policy Mexico. Pursuant to federal law, the Bureau of Reclamation (part of the Department of the Interior) manages much of the basin’s water supplies. Colorado River water is used Pervaze A. Sheikh primarily for agricultural irrigation and municipal and industrial (M&I) uses, but it also Specialist in Natural is important for power production, fish and wildlife, and recreational uses. Resources Policy In recent years, consumptive uses of Colorado River water have exceeded natural flows. This causes an imbalance in the basin’s available supplies and competing demands. A drought in the basin dating to 2000 has raised the prospect of water delivery curtailments and decreased hydropower production, among other things. In the future, observers expect that increasing demand for supplies, coupled with the effects of climate change, will further increase the strain on the basin’s limited water supplies. River Management The Law of the River is the commonly used shorthand for the multiple laws, court decisions, and other documents governing Colorado River operations. The foundational document of the Law of the River is the Colorado River Compact of 1922. Pursuant to the compact, the basin states established a framework to apportion the water supplies between the Upper and Lower Basins of the Colorado River, with the dividing line between the two basins at Lee Ferry, AZ (near the Utah border).
