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.

Lake Mead National Recreation Area Draft Quagga Mussel Initial Response Plan
Lake Mead National Recreation Area Draft Quagga Mussel Initial Response Plan Executive Summary Quagga mussels, closely related to zebra mussels, were first discovered at Lake Mead National Recreation Area (Lake Mead NRA) on January 6, 2007, the first detection of this species in the western United States. These invasive freshwater mussels are expected to cause major impacts to biological resources, submerged cultural resources, marinas, water intakes, boats and recreational use in the Lower Colorado River System and, if spread, pose similar threats to other western waters. The National Park Service led a three month interagency initial response effort focused on assessment, containment, treatment, and long-term management of the quagga mussel infestation in Lakes Mead and Mohave. This effort culminated in an Initial Response Plan. When no treatment or eradication methods were found to be feasible at this time, the efforts focused on containment of spread to other watersheds. The highlights of the initial response effort include: • Interagency planning at the local level with close coordination with concurrent upstream and downstream planning efforts as well as significant input from the scientific community • Increased emphasis on the pre-existing invasive aquatic species prevention and early detection program • Assessment and monitoring of adult and juvenile quagga mussel populations in Lakes Mead and Mohave • Containment strategy focused on mandatory cleaning upon entry and exit for all slipped and moored boats • New special use permit

Lake Powell Mansour Sharifzadeh, (E-Mail: [email protected]), California State Polytechnic University, Pomona
Journal of Business Case Studies – Second Quarter 2007 Volume 3, Number 2 Lake Powell Mansour Sharifzadeh, (E-mail: [email protected]), California State Polytechnic University, Pomona ABSTRACT The purpose of the “Lake Powell’ case is to help students of Strategic Management learn the process of strategic management. This case can provide an opportunity for the students to learn strategy formulation and implementation along with some of the current issues such as “cooking the books”. Some sections of the Lake Powell case are real life situations, but all of the numbers and most of operations information are fictitious. Four experienced and knowledgeable men started Lake Powell Company with many opportunities and strength. However the company has lost money in the last five years. Students analyze, formulate and write an implementation of a strategy to save this company. Students then try to answer the following questions. What should be the proposed plan to Richmond for the Marina in order to have an effective, efficient, and profitable operation? How would it be funded? However the instructor will look at other scenarios and ask the students to figure out the four partner’s real goal. THE SETTING ake Powell is located between the borderline of Arizona and Utah along the Colorado River. It has a spectacular scenery view from Grand Canyon, vivid pink sunset, to a full night of stars. The possibilities L of fishing, skiing, or living in the houseboat on the brilliant blue water are other options to consider. It is nearly two thousand miles of shoreline, 96 major canyons, countless coves and winding waterways.

FINAL Retrospective Analysis of Water Temperature Data and Larval And
FINAL Retrospective analysis of water temperature data and larval and young of year fish collections in the San Juan River downstream from Navajo Dam to Lake Powell Utah Prepared for: Ecosystems Research Institute Logan, Utah And U.S. Bureau of Reclamation Salt Lake City, Utah Prepared by: William J. Miller And Kristin M. Swaim Miller Ecological Consultants, Inc PO Box 1383 Bozeman, Montana 59771 February 14, 2017 Final San Juan River Water Temperature Retrospective Report February 14, 2017 Executive Summary Miller Ecological Consultants conducted a retrospective analysis of existing San Juan River water temperature datasets and larval fish data. Water temperature data for all years available were evaluated in conjunction with the timing and number of larvae captured in the annual larval fish monitoring surveys that are required by the San Juan River Basin Recovery Implementation Program (SJRBRIP) Long Range Plan. Under the guidance of the SJRBRIP, Navajo Dam experimental releases were conducted and evaluated from 1992-1998. After this research period, the SJRBRIP completed the flow recommendations. The SJRBRIP established flow recommendations for the San Juan River designed to maintain or improve habitat for endangered Colorado Pikeminnow Ptychocheilus lucius and Razorback Sucker Xyrauchen texanus by modifying reservoir release patterns from Navajo Dam (Holden 1999). The flow recommendations were designed to mimic the natural hydrograph or flow regime in terms of magnitude, duration and frequency of flows. Water is released from the deep hypolimnetic zone of the reservoir, which results in water temperatures that are cooler than natural, pre-dam conditions. Water temperatures in the San Juan River have been monitored and recorded at several locations as part of the SJRBRIP since 1992.

Hidden Passage
Hidden Passage the journal of glen canyon institute Issue XIX, Fall 2013 Glen Canyon Institute An Answer for the Colorado River: Fill Mead First President Richard Ingebretsen by Wade Graham Board of Trustees Barbara Brower In this issue of Hidden Passage, we present Glen Canyon Institute’s Fill Mead First Scott Christensen plan to begin the transition to a more sustainable management system on the Ed Dobson Colorado River, by saving significant amounts of water lost to seepage and taking David Wegner large steps towards the restoration of Glen and Grand Canyons. The plan is Wade Graham buttressed by an important new hydrological study demonstrating that Tyler Coles consolidating water storage in Lake Mead and keeping Lake Powell at its Lea Rudee minimum active power pool elevation can save between 300,000 and 600,000 acre-feet of water per year. Executive Director Christi Wedig Change is coming to the Colorado River, for better or worse, both due to climate Program Director change and to ever-increasing demands on an over-committed resource. It is past Michael Kellett time for those who care about the river basin’s human and natural communities to Office and Projects Manager begin making common sense but determined changes to the way the river is Mike Sargetakis managed. Programs Coordinator Eric Balken A study of water supply and demand in the Colorado River Basin released last December by the Bureau of Reclamation confirms what everyone already Advisory Committee Dan Beard knew: we are sucking more water out of the river than nature is putting in.
