Book Description
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.

Book Description
Over the past century, humans have molded the Colorado River to serve their own needs, resulting in significant impacts to the river and its ecosystems. Today, many scientists, public officials, and citizens hope to restore some of the lost resources in portions of the river and its surrounding lands. Environmental restoration on the scale of the Colorado River basin is immensely challenging; in addition to an almost overwhelming array of technical difficulties, it is fraught with perplexing questions about the appropriate goals of restoration and the extent to which environmental restoration must be balanced against environmental changes designed to promote and sustain human economic development. Restoring Colorado River Ecosystems explores the many questions and challenges surrounding the issue of large-scale restoration of the Colorado River basin, and of large-scale restoration in general. Robert W. Adler evaluates the relationships among the laws, policies, and institutions governing use and management of the Colorado River for human benefit and those designed to protect and restore the river and its environment. He examines and critiques the often challenging interactions among law, science, economics, and politics within which restoration efforts must operate. Ultimately, he suggests that a broad concept of “restoration” is needed to navigate those uncertain waters, and to strike an appropriate balance between human and environmental needs. While the book is primarily about restoration of Colorado River ecosystems, it is also about uncertainty, conflict, competing values, and the nature, pace, and implications of environmental change. It is about our place in the natural environment, and whether there are limits to that presence we ought to respect. And it is about our responsibility to the ecosystems we live in and use.

Book Description
Grant Stevens, a mid-level manager for the Bureau of Reclamation, only wanted to build dams. He never imagined he would be swept into a desperate race against an environmental terrorist bent on restoring the Colorado River by blowing up the dams. Left temporarily in charge of the Bureau, Grant must react when the first dam is attacked. He faces the unthinkable task of mitigating the massive flood roaring down the Colorado. The flood will eventually threaten the mighty Hoover Dam, and if Hoover fails, the other dams downstream will fall like dominos. Working with the FBI, Grant uses his engineering skills, river knowledge, and plenty of gut instinct in an attempt to outmaneuver the terrorist. The chase will lead all the way downstream to the Gulf of California in a cat and mouse game where the stakes are high and the potential for destruction is enormous.

Book Description
“I’ve been thinking a lot about Cadillac Desert in the past few weeks, as the rain fell and fell and kept falling over California, much of which, despite the pouring heavens, seems likely to remain in the grip of a severe drought. Reisner anticipated this moment. He worried that the West’s success with irrigation could be a mirage — that it took water for granted and didn’t appreciate the precariousness of our capacity to control it.” – Farhad Manjoo, The New York Times, January 20,2023 "The definitive work on the West's water crisis." --Newsweek The story of the American West is the story of a relentless quest for a precious resource: water. It is a tale of rivers diverted and dammed, of political corruption and intrigue, of billion-dollar battles over water rights, of ecological and economic disaster. In his landmark book, Cadillac Desert, Marc Reisner writes of the earliest settlers, lured by the promise of paradise, and of the ruthless tactics employed by Los Angeles politicians and business interests to ensure the city's growth. He documents the bitter rivalry between two government giants, the Bureau of Reclamation and the U.S. Army Corps of Engineers, in the competition to transform the West. Based on more than a decade of research, Cadillac Desert is a stunning expose and a dramatic, intriguing history of the creation of an Eden--an Eden that may only be a mirage. This edition includes a new postscript by Lawrie Mott, a former staff scientist at the Natural Resources Defense Council, that updates Western water issues over the last two decades, including the long-term impact of climate change and how the region can prepare for the future.
