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
For over a century, the federal government has constructed water resource projects for a variety of purposes, including flood control, navigation, power generation, and irrigation. While most municipal and industrial water supplies have been built by non-federal entities, most of the large, federal water supply projects in the West, including Hoover and Grand Coulee dams, were constructed by the Bureau of Reclamation (Department of the Interior) to provide water for irrigation. Growing populations and changing values have increased demands on water supplies and river systems, resulting in water use and management conflicts throughout the country, particularly in the West, where the population is expected to increase 30% in the next 20-25 years. In many western states, agricultural needs are often in direct conflict with urban needs, as well as with water demand for threatened and endangered species, recreation, and scenic enjoyment. Debate over western water resources revolves around the issue of how best to plan for and manage the use of this renewable, yet sometimes scarce and increasingly sought after, resource. Some observers advocate enhancing water supplies, for example, by building new storage or diversion projects, expanding old ones, or funding water reclamation and reuse facilities. Others emphasise the need to manage existing supplies more efficiently through conservation, revision of policies that encourage inefficient use of water, and establishment of market mechanisms to allocate water. Recent proposals to expand the Upper Mississippi River-Illinois Waterway (UMR-IWW) a major transportation route for products moving to and from Illinois, Iowa, Minnesota, Missouri, and Wisconsin have met with significant controversy. Some of this controversy centres on the cumulative environmental effects of the current navigation system and the proposed expansion. The Upper Mississippi River System (UMRS), which includes the navigation channel and surrounding floodplain supports an unusually large number of species for a temperate river. The UMR-IWW navigation system alters UMRS habitat and contributes to a decline in the abundance of some species. For example, locks, dams, and other channel structures inhibit the movement of fish between and within river segments; fill side channels, backwaters, and wetlands with sediment; and suppress plant growth by reducing water clarity.

Book Description
In 1919, a Canadian teenager with a sixth-grade education arrived by train to the wilds of Los Angeles. Within a decade he had transformed himself into a world-renowned luminary and occult scholar. His name was Manly Palmer Hall, author of the landmark encyclopedia The Secret Teachings of All Ages and the 20th century's most prolific writer and speaker on ancient philosophies, mysticism, and magic. Hall revealed to thousands how universal wisdom could be found in the myths and symbols of the ancient Western mystery teachings. He amassed the largest occult library west of the Mississippi and founded The Philosophical Research Society in 1934 for the purpose of providing seekers rare access to the world's wisdom literature. He became a confidante and friend to celebrities and politicians. In 1990, he died - some say he was killed - in what remains an open-ended Hollywood murder mystery. This dramatic story of Hall's life and death provides a panorama of twentieth century mysticism and an insider's view into a subculture that continues to have a profound influence on movies, television, music, books, art, and thought.

Book Description
Discusses the history of the U.S. Bureau of Reclamation's operation and management of the Colorado River on behalf of the Secretary of the Interior from 1979 through 2008. Details the political, legal, institutional, and other instruments developed to address pressing issues faced by Colorado River Basin water users and managers. Reflective of its era, the 2008 volume has an increased focus on coordinated operations of the river in both the Upper and Lower Basins, on environmental matters, on the relationship with Mexico, and on Native American water settlements.
