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 Yampa River is the longest relatively free-flowing river Water has always been in short supply in the western reach remaining in the Colorado River basin. The U.S., making it a consistent source of conflict. In Green River is highly regulated by Flaming Gorge Dam the Colorado River drainage, an increasing human but is partially restored below its confluence with the population fuels increased demands for water from Yampa River. There have been large-scale changes the river and its tributaries. As a result, streamflow to the Green River since Flaming Gorge Dam was in virtually all of these systems has been altered by completed in 1962. reservoirs and other water-development projects. In most cases, reduced flows have significantly altered Monitoring of these rivers and their riparian peak flows and increased base flows that structure vegetation focuses on processes that affect the river floodplain vegetation, stream-channel morphology, channel, active bars, and riparian floodplains.

C.; Callender, J. F.; [eds.], New Mexico Geological Society 32nd Annual Fall Field Conference Guidebook, 337 p. This is one of many related papers that were included in the 1981 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

Flaming Gorge Operation Plan - May 2021 Through April 2022
Flaming Gorge Operation Plan - May 2021 through April 2022 Concurrence by Kathleen Callister, Resources Management Division Manager Kent Kofford, Provo Area Office Manager Nicholas Williams, Upper Colorado Basin Power Manager Approved by Wayne Pullan, Upper Colorado Basin Regional Director U.S. Department of the Interior Bureau of Reclamation • Interior Region 7 Upper Colorado Basin • Power Office Salt Lake City, Utah May 2021 Purpose This Flaming Gorge Operation Plan (FG-Ops) fulfills the 2006 Flaming Gorge Record of Decision (ROD) requirement for May 2021 through April 2022. The FG-Ops also completes the 4-step process outlined in the Flaming Gorge Standard Operation Procedures. The Upper Colorado Basin Power Office (UCPO) operators will fulfil the operation plan and may alter from FG-Ops due to day to day conditions, although we will attempt to stay within the boundaries of the operations defined below. Listed below are proposed operation plans for four different scenarios: moderately dry, average (above median), average (below median), and moderately wet. As of the publishing of this document, the most likely scenario is the moderately dry, however actual operations will vary with hydrologic conditions. The Upper Colorado River Endangered Fish Recovery Program (Recovery Program), the Flaming Gorge Technical Working Group (FGTWG), Flaming Gorge Working Group (FG WG), United States Fish and Wildlife Service (FWS) and Western Area Power Administration (WAPA) provided input that was considered in the development of this report. The FG-Ops describes the current hydrologic classification of the Green River Basin and the hydrologic conditions in the Yampa River Basin. The FG-Ops identifies the most likely Reach 2 peak flow magnitude and duration that is to be targeted for the upcoming spring flows. -
FIXING the UPPER COLORADO RIVER Paul Bruchez, Reeder
FIXING THE UPPER COLORADO RIVER Paul Bruchez, Reeder Creek Ranch Mely Whiting, Colorado Counsel, Trout Unlimited Lurline Curran, former Grand County manager Grand County’s most famous tourist was President Dwight Eisenhower, who in the 1950s spent summer vacations snagging trout from the Fraser River. That river even then was significantly depleted by diversion to Denver. Nearby, at Grand Lake, the Colorado-Big Thompson (C-BT) had begun a massive withdrawal of water from the Colorado River. Later, in the 1980s, came another major disruption to the local water-dependent ecosystems, a dam on the Colorado River near Windy Gap, where it is joined by the Fraser. It all adds up to what rancher and fishing guide Paul Bruchez described as death by a thousand cuts. The full extent of the problems became apparent in the 2002 drought and its aftermath. In old days, before all the diversions began, ranchers in the Kremmling area had just relied upon springtime snowmelt flooding by the river to deliver water to their hay fields. Because of the C-BT diversions, the U.S. Bureau of Reclamation had installed pumps along the river, to ensure ranchers could get water into the fields. As river flows receded in the 21st century, those pumps had become inadequate even as Denver Water and Northern Water (beneficiary of the C-BT) pushed long-standing plans for further diversions. The net result: 80 percent of native flows in the Colorado River would be diverted across the Continental Divide. This could have gotten ugly, but Grand County instead chose a different approach. -
