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.

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 of 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 non-lawyers involved in water quality issues, students, and attorneys and water professionals desiring a succinct and readable summary of Colorado water law, as well as general readers interested in Colorado's complex water rights law.
