3.6 Riverflow Issues
AFFECTED ENVIRONMENT & ENVIRONMENTAL CONSEQUENCES CHAPTER 3 3.6 RIVERFLOW ISSUES 3.6.1 INTRODUCTION This section considers the potential effects of interim surplus criteria on three types of releases from Glen Canyon Dam and Hoover Dam. The Glen Canyon Dam releases analyzed are those needed for restoration of beaches and habitat along the Colorado River between the Glen Canyon Dam and Lake Mead, and for a yet to be defined program of low steady summer flows to be provided for the study and recovery of endangered Colorado River fish, in years when releases from the dam are near the minimum. The Hoover Dam releases analyzed are the frequency of flood releases from the dam and the effect of flood flows along the river downstream of Hoover Dam. 3.6.2 BEACH/HABITAT-BUILDING FLOWS The construction and operation of Glen Canyon Dam has caused two major changes related to sediment resources downstream in Glen Canyon and Grand Canyon. The first is reduced sediment supply. Because the dam traps virtually all of the incoming sediment from the Upper Basin in Lake Powell, the Colorado River is now released from the dam as clear water. The second major change is the reduction in the high water zone from the level of pre-dam annual floods to the level of powerplant releases. Thus, the height of annual sediment deposition and erosion has been reduced. During the investigations leading to the preparation of the Operation of Glen Canyon Dam Final EIS (Reclamation, 1995b), the relationships between releases from the dam and downstream sedimentation processes were brought sharply into focus, and flow patterns designed to conserve sediment for building beaches and habitat (i.e., beach/habitat-building flow, or BHBF releases) were identified. -
ATTACHMENT B Dams and Reservoirs Along the Lower
ATTACHMENTS ATTACHMENT B Dams and Reservoirs Along the Lower Colorado River This attachment to the Colorado River Interim Surplus Criteria DEIS describes the dams and reservoirs on the main stream of the Colorado River from Glen Canyon Dam in Arizona to Morelos Dam along the international boundary with Mexico. The role that each plays in the operation of the Colorado River system is also explained. COLORADO RIVER INTERIM SURPLUS CRITERIA DRAFT ENVIRONMENTAL IMPACT STATEMENT COLORADO RIVER DAMS AND RESERVOIRS Lake Powell to Morelos Dam The following discussion summarizes the dams and reservoirs along the Colorado River from Lake Powell to the Southerly International Boundary (SIB) with Mexico and their specific roles in the operation of the Colorado River. Individual dams serve one or more specific purposes as designated in their federal construction authorizations. Such purposes are, water storage, flood control, river regulation, power generation, and water diversion to Arizona, Nevada, California, and Mexico. The All-American Canal is included in this summary because it conveys some of the water delivered to Mexico and thereby contributes to the river system operation. The dams and reservoirs are listed in the order of their location along the river proceeding downstream from Lake Powell. Their locations are shown on the map attached to the inside of the rear cover of this report. Glen Canyon Dam – Glen Canyon Dam, which formed Lake Powell, is a principal part of the Colorado River Storage Project. It is a concrete arch dam 710 feet high and 1,560 feet wide. The maximum generating discharge capacity is 33,200 cfs which may be augmented by an additional 15,000 cfs through the river outlet works. -

Colorado River Slideshow Title TK
The Colorado River: Lifeline of the Southwest { The Headwaters The Colorado River begins in the Rocky Mountains at elevation 10,000 feet, about 60 miles northwest of Denver in Colorado. The Path Snow melts into water, flows into the river and moves downstream. In Utah, the river meets primary tributaries, the Green River and the San Juan River, before flowing into Lake Powell and beyond. Source: Bureau of Reclamation The Path In total, the Colorado River cuts through 1,450 miles of mountains, plains and deserts to Mexico and the Gulf of California. Source: George Eastman House It was almost 1,500 years ago when humans first tapped the river. Since then, the water has been claimed, reclaimed, divided and subdivided many times. The river is the life source for seven states – Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming – as well as the Republic of Mexico. River Water Uses There are many demands for Colorado River water: • Agriculture and Livestock • Municipal and Industrial • Recreation • Fish/Wildlife and Habitat • Hydroelectricity • Tribes • Mexico Source: USGS Agriculture The Colorado River provides irrigation water to about 3.5 million acres of farmland – about 80 percent of its flows. Municipal Phoenix Denver About 15 percent of Colorado River flows provide drinking and household water to more than 30 million people. These cities include: Las Vegas and Phoenix, and cities outside the Basin – Denver, Albuquerque, Salt Lake City, Los Angeles, San Diego and Tijuana, Mexico. Recreation Source: Utah Office of Tourism Source: Emma Williams Recreation includes fishing, boating, waterskiing, camping and whitewater rafting in 22 National Wildlife Refuges, National Parks and National Recreation Areas along river. -

4 The Colorado River: lifeline of the American Southwest Clarence A. Carlson Department of Fishery and Wildlife Biology, Colorado State University, Fort Collins, CO, USA 80523 Robert T. Muth Larval Fish Laboratory, Colorado State University, Fort Collins, CO, USA 80523 1 Carlson, C. A., and R. T. Muth. 1986. The Colorado River: lifeline of the American Southwest. Can. J. Fish. Aguat. Sci. In less than a century, the wild Colorado River has been drastically and irreversibly transformed into a tamed, man-made system of regulated segments dominated by non-native organisms. The pristine Colorado was characterized by widely fluctuating flows and physico-chemical extremes and harbored unique assemblages of indigenous flora and fauna. Closure of Hoover Dam in 1935 marked the end of the free-flowing river. The Colorado River System has since become one of the most altered and intensively controlled in the United States. Many main-stem and tributary dams, water diversions, and channelized river sections now exist in the basin. Despite having one of - the most arid drainages in the world, the present-day Colorado River supplies more water for consumptive use than any river in the United States. Physical modification of streams and introduction of non-native species have adversely impacted the Colorado's native biota. This paper treats the Colorado River holistically as an ecosystem and summarizes current knowledge on its ecology and management. "In a little over two generations, the wild Colorado has been harnessed by a series of dams strung like beads on a thread from the Gulf of California to the mountains of Wyoming. -
