The document discusses managing water storage for multiple uses and users. It provides examples from various projects around the world of integrating water management for livestock, ecosystems, fisheries, crops and other uses. This includes balancing livestock and water needs, managing fresh and brackish water in river systems, and developing tools and techniques for planning and managing small reservoirs to meet diverse water needs. The document proposes areas of further research on evaluating tradeoffs of multiple use systems and enabling supportive policies and institutions.
