Recent studies of past climate and streamflow conditions have broadened understanding of long-term water availability in the Colorado River, revealing many periods when streamflow was lower than at any time in the past 100 years of recorded flows. That information, along with two important trends-a rapid increase in urban populations in the West and significant climate warming in the region-will require that water managers prepare for possible reductions in water supplies that cannot be fully averted through traditional means. Colorado River Basin Water Management assesses existing scientific information, including temperature and streamflow records, tree-ring based reconstructions, and climate model projections, and how it relates to Colorado River water supplies and demands, water management, and drought preparedness. The book concludes that successful adjustments to new conditions will entail strong and sustained cooperation among the seven Colorado River basin states and recommends conducting a comprehensive basinwide study of urban water practices that can be used to help improve planning for future droughts and water shortages.

This book addresses the fundamental requirement for aninterdisciplinary catchment based approach to managing andprotecting water resources that crucially includes anunderstanding of land use and its management. In thisapproach the hydrological cycle links mountains to the sea, andecosystems in rivers, groundwaters, lakes, wetlands, estuaries andcoasts forming an essential continuum directly influenced by humanactivity. The book provides a synthesis of current and future thinking incatchment management, and shows how the specific problems thatarise in water use policy can be addressed within the context of anintegrated approach to management. The book is written for advancedstudents, researchers, fellow academics and water sectorprofessionals such as planners and regulators. The intention is tohighlight examples and case studies that have resonance not onlywithin natural sciences and engineering but with academicsin other fields such as socio-economics, law and policy.

Science Be Dammed is an alarming reminder of the high stakes in the management—and perils in the mismanagement—of water in the western United States. It seems deceptively simple: even when clear evidence was available that the Colorado River could not sustain ambitious dreaming and planning by decision-makers throughout the twentieth century, river planners and political operatives irresponsibly made the least sustainable and most dangerous long-term decisions. Arguing that the science of the early twentieth century can shed new light on the mistakes at the heart of the over-allocation of the Colorado River, authors Eric Kuhn and John Fleck delve into rarely reported early studies, showing that scientists warned as early as the 1920s that there was not enough water for the farms and cities boosters wanted to build. Contrary to a common myth that the authors of the Colorado River Compact did the best they could with limited information, Kuhn and Fleck show that development boosters selectively chose the information needed to support their dreams, ignoring inconvenient science that suggested a more cautious approach. Today water managers are struggling to come to terms with the mistakes of the past. Focused on both science and policy, Kuhn and Fleck unravel the tangled web that has constructed the current crisis. With key decisions being made now, including negotiations for rules governing how the Colorado River water will be used after 2026, Science Be Dammed offers a clear-eyed path forward by looking back. Understanding how mistakes were made is crucial to understanding our contemporary problems. Science Be Dammed offers important lessons in the age of climate change about the necessity of seeking out the best science to support the decisions we make.

Proper management of water resources can take many forms, and requires the knowledge and expertise to work at the intersection of mathematics, geology, biology, geography, meteorology, political science, and even psychology. This book provides an essential foundation in water management and development concepts and practices, dissecting complex topics into short, understandable explanations that spark true interest in the field. Approaching the study of water resources systematically, the discussion begins with historical perspective before moving on to physical processes, engineering, water chemistry, government regulation, environmental issues, global conflict, and more. Now in its fourth edition, this text provides the most current introduction to a field that is becoming ever more critical as climate change begins to threaten water supplies around the world. As geography, climate, population growth, and technology collide, effective resource management must include a comprehensive understanding of how these forces intermingle and come to life in the water so critical to us all.

Co-management is a highly dynamic, evolving, adaptive, and forward looking process. This edited volume covers theoretical background and includes supporting lessons learnt from field experiences. The book has case studies from both North and South America (co-management of fisheries, resilience in near-shore waters of the Great Lakes

Sustainability and Water Management in the Maya World and Beyond investigates climate change and sustainability through time, exploring how political control of water sources, maintenance of sustainable systems, ideological relationships with water, and fluctuations in water availability have affected and been affected by social change. Contributors focus on and build upon earlier investigations of the global diversity of water management systems and the successes and failures of their employment, while applying a multitude of perspectives on sustainability. The volume focuses primarily on the Precolumbian Maya but offers several analogous case studies outside the ancient Maya world that illustrate the pervasiveness of water’s role in sustainability, including an ethnographic study of the sustainability of small-scale, farmer-managed irrigation systems in contemporary New Mexico and the environmental consequences of Angkor’s growth into the world’s most extensive preindustrial settlement. The archaeological record offers rich data on past politics of climate change, while epigraphic and ethnographic data show how integrated the ideological, political, and environmental worlds of the Maya were. While Sustainability and Water Management in the Maya World and Beyond stresses how lessons from the past offer invaluable insight into current approaches of adaptation, it also advances our understanding of those adaptations by making the inevitable discrepancies between past and present climate change less daunting and emphasizing the sustainable negotiations between humans and their surroundings that have been mediated by the changing climate for millennia. It will appeal to students and scholars interested in climate change, sustainability, and water management in the archaeological record.

Why do people fight about water rights? Who decides how much water can be used by a city or irrigator? Does the federal government get involved in state water issues? Why is water in Colorado so controversial? These questions, and others like them, are addressed in Colorado Water Law for Non-Lawyers. This concise and understandable treatment of the complex web of Colorado water laws is the first book of its kind. Legal issues related to water rights in Colorado first surfaced during the gold mining era in the 1800s and continue to be contentious today with the explosive population growth of the twenty-first century. Drawing on geography and history, the authors explore the flashpoints and water wars that have shaped Colorado’s present system of water allocation and management. They also address how this system, developed in the mid-1800s, is standing up to current tests—including the drought of the past decade and the competing interests for scarce water resources—and predict how it will stand up to new demands in the future. This book will appeal to at students, non-lawyers involved with water issues, and general readers interested in Colorado’s complex water rights law.
