Comprehensive Review of the Fill Lake Mead First Initiative
Comprehensive Review of the Fill Lake Mead First Initiative Trevor Carey ECL 290 February 28th, 2018 Lake Powell • Commissioned in 1966, full pool 1980 • 2nd largest man-made reservoir in United States (24.3 MAF) • Important for water storage and power generation for the Western United States USBR (2015) Impacts of Lake Powell and Glen Canyon Dam Fish Mollie & Aviva: Showed the dam almost eliminated sediment flows, decreased river temp. and allowed for a more hospitable environment for non-native fish. Vanessa: Discussed how dams contributed the extirpation of native fish. Water Rights Jesse & Jennifer: Native American’s access to water rights in the upper and lower basin, (Navajo water rights are in the Lake Powell watershed). Sediment Jeff: Sediment regime of the lower basin has been completely altered by impoundment of Lake Powell. Sarah: How dams contributed to changes to riparian ecosystems. Jasmin: Using high flow experiments to redistribute sediment and create beaches Dam Operation Marisa: Citizen science program looking at tidal effects caused by the dam Other Ann: Habitat destruction of the Kanab Ambersnail from high flows Fill Lake Mead First Initiative • Reservoir levels of both Lake Mead & Powell have been hovering around 50% full • Recent studies Barnett and Pierce (2008) and Kirk et al. (2017) showed reservoir levels will continue to decline, and hot drier conditions will be more common • Drain water from Lake Powell to fill Lake Mead • Glen Canyon dam would become a run of the river dam, with additional flood control capacity if needed Data courtesy of water-data.com Goals of FLMF • First proposed by Glen Canyon Institute in 2013 • Identified 3 goals of the initiative: 1. -
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. -

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. -
Fill Mead First: a Technical Assessment1 Executive Summary
Fill Mead First: a technical assessment1 John C. Schmidt2 with contributions from Maggi Kraft3, Daphnee Tuzlak4, and Alex Walker3 White Paper No. 1 Center for Colorado River Studies Quinney College of Natural Resources Utah State University November 10, 2016 Executive Summary The Fill Mead First (FMF) plan would establish Lake Mead reservoir as the primary water storage facility of the main-stem Colorado River and would relegate Lake Powell reservoir to a secondary water storage facility to be used only when Lake Mead is full. The objectives of the FMF plan are to re-expose some of Glen Canyon’s sandstone walls that are now inundated, begin the process of re-creating a riverine ecosystem in Glen Canyon, restore a more natural stream-flow, temperature, and sediment-supply regime of the Colorado River in the Grand Canyon ecosystem, and reduce system-wide water losses caused by evaporation and movement of reservoir water into ground-water storage. The FMF plan would be implemented in three phases. Phase I would involve lowering Lake Powell to the minimum elevation at which hydroelectricity can still be produced (called minimum power pool elevation): 3490 ft asl (feet above sea level). At this elevation, the water surface area of Lake 1 suggested citation: Schmidt, J. C., Kraft, M., Tuzlak, D., and Walker, A. 2016. Fill Mead First: a technical assessment.
