Available in PDF, EPUB and Kindle. Book excerpt: An audit of the Bureau of Reclamation's (BoR) final Environmental Impact Statement (EIS) on the operations of the Glen Canyon Dam (GCD). This report discusses: whether BoR's determination of the impact of various dam-operating alternatives on selected resources was reasonable; and what, if any, concerns still exist on the part of key interested parties about the final EIS. Since the GCD, located in Page, AZ, was completed by the BoR in 1963, it has been used to generate power during periods of high demand. The fluctuation releases of water have caused concerns about the detrimental effects such flows have in the Grand Canyon.

Available in PDF, EPUB and Kindle. Book excerpt: Photographs made in Grand Canyon a century ago may provide us with a sense of history; photographs made today from the same vantage points give us a more precise picture of change in this seemingly timeless place. Between 1889 and 1890, Robert Brewster Stanton made photographs every one to two miles through the river corridor for the purpose of planning a water-level railroad route; he produced the largest collection of photographs of the Colorado River at one point in time. Robert Webb, a USGS hydrologist conducting research on debris flows in the Canyon, obtained the photographs, and from 1989 to 1995, he replicated all 445 of the views captured by Stanton, matching as closely as possible the original camera positions and lighting conditions. Grand Canyon, a Century of Change assembles the most dramatic of these paired photographs to demonstrate both the persistence of nature and the presence of humanity. The level of detail obtained from the photographs represent one of the most extensive long-term monitoring efforts ever conducted in a national park and the most detailed documentation effort ever performed using repeat photography. Much more than simply a picture book, Grand Canyon, a Century of Change is an environmental history of the river corridor, a fascinating book that clearly shows the impact of human influence on Grand Canyon and warns us that the Canyon's future is very much in our hands.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 110. The natural flow of almost every river in the United States has been modified to meet various socioeconomic goals—navigation, irrigation, power generation and flood control. The success of the dams and reservoirs built to achieve these goals has been accompanied by changes in the status of riverine resources downstream, a cause of growing environmental and ecological concern. For example, before Glen Canyon Dam was completed, the Colorado River transported large quantities of sediment in floods as large as 8500 m3/s. After the dam was closed in 1963, dam releases typically were less than the powerplant capacity of 890 m3/s and exhibited large daily flow fluctuations. The river carried little sediment. The daily fluctuations in flow eroded sand bars, and the smaller, controlled flow did not redeposit them. The clear, cold water resulted in increased aquatic productivity such that rainbow trout and other nonnative fishes thrived while most native species were lost or endangered.
