This special collection of the Journal of Water Resources Planning and Management focuses on water resources and environmental planning, reservoir operations, policy, climate and hydrology, water demand, and economics related to management of the Colorado River system. The Colorado River and its tributaries extend into seven states and Mexico, contributing to the social and economic well-being for millions of people and providing essential environmental benefits. Over 40 million people in the United States and Mexico rely on the Colorado River system for agricultural and municipal water supply. Approximately 5.5 million acres within the United States and nearly 500,000 acres within Mexico are irrigated using Colorado River water. The Colorado River is highly managed and faces significant challenges in the long-term from a growing population and a changing climate, and the more immediate crises created by a widespread and continuing 20-year drought.
