The Grand Canyon Monitoring and Research Center began long-term planning at its inception and, in May 1997, produced a Long-Term Monitoring and Research Strategic Plan that was adopted by stakeholder groups (the Adaptive Management Work Group and the Technical Work Group) later that year. The Center then requested the National Research Council's (NRC) Water Science and Technology Board to evaluate this plan.

Adjustment to the environmental alterations of the Glen Canyon Dam.

This book contains 11 papers that review the extant information about the Colorado River from an ecosystem perspective and serve as the basis for discussion of the use of ecosystem/earth science information for river management and dam operations. It also contains a synopsis of the committee's findings and recommendations to the Bureau of Reclamation as the agency seeks to change its direction to the management of natural resources.

Federal management of water is undergoing a change that involves a drastic reduction in the number of new water projects and an increase in emphasis on the quality of water management. This book summarizes and analyzes environmental research conducted in the lower Colorado River below the Glen Canyon Dam under the leadership of the Bureau of Reclamation. It reviews alternative dam operations to mitigate impacts in the lower Colorado riverine environment and the strengths and weaknesses of large federal agencies dealing with broad environmental issues and hydropower production. While many problems remain to be solved, the Bureau of Reclamation through the Glen Canyon area. The lessons of GCES are transferable to other locations and could be the basis for a new era in the management of western waters.

"In 1996, author and photographer Michael Collier set out in his forty-year-old Cessna seeking an expanded understanding and perspective on the Colorado River basin - a region spanning the states of Wyoming, Utah, Colorado, Nevada, California, Arizona, and New Mexico - which he had come to know intimately through twenty-five years of river running. Twelve thousand photographs and more than a year later, Collier had learned another way of knowing that magnificent landscape and now shares his altered vision in Water, Earth, and Sky: The Colorado River Basin." "One hundred forty images are accompanied by six essays, written by experts in various fields of natural history and ecology, that illuminate chosen aspects of this landscape."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Every writer comes to the Colorado River in the Grand Canyon with a unique point of view. Ann Zwinger's is that of a naturalist, an "observer at the river's brim." Teamed with scientists and other volunteer naturalists, Zwinger was part of an ongoing study of change along the Colorado. In all seasons and all weathers, in almost every kind of craft that goes down the waves, she returned to the Grand Canyon again and again to explore, look, and listen. From the thrill of running the rapids to the wonder in a grain of sand, her words take the reader down 280 miles of the "ever-flowing, energetic, whooping and hollering, galloping" river. Zwinger's book begins with a bald eagle count at Nankoweap Creek in January and ends with a subzero, snowy walk out of the canyon at winter solstice. Between are the delights of spring in side canyons, the benediction of rain on a summer beach, and the chill that comes off limestone walls in November. Her eye for detail catches the enchantment of small things played against the immensity of the river: the gatling-gun love song of tree frogs; the fragile beauty of an evening primrose; ravens "always in close attendance, like lugubrious, sharp-eyed, nineteenth-century undertakers"; and a golden eagle chasing a trout "with wings akimbo like a cleaning lady after a cockroach." As she travels downstream, Zwinger follows others in history who have risked—and occasionally lost—their lives on the Colorado. Hiking in narrow canyons, she finds cliff dwellings and broken pottery of prehistoric Indians. Rounding a bend or running a rapid, she remembers the triumphs and tragedies of early explorers and pioneers. She describes the changes that have come with putting a big dam on a big river and how the dam has affected the riverine flora and fauna as well as the rapids and their future. Science in the hands of a poet, this captivating book is for armchair travelers who may never see the grandiose Colorado and for those who have run it wisely and well. Like the author, readers will find themselves bewitched by the color and flow of the river, and enticed by what's around the next bend. With her, they will find its rhythms still in the mind, long after the splash and spray and pound are gone.
