Our Challenge
Can multi-sector benefits from water transactions programs be measured in a standardized way, and if so, might the transparency around the benefits help to drive multi-sector collaboration?
In the western United States, where water rights are rigidly allocated by seniority, water transactions are a powerful tool for restoring streamflow to depleted rivers and streams, and for adapting to scarcity and uncertainty in water supply. This team has developed a suite of standardized indicators for measuring the benefits and impacts of water transaction programs. Together, the indicators help water managers understand and quantify potential tradeoffs and synergies among alternative water transaction strategies and programs for different water sectors. Additionally, they provide an understanding of how water sharing agreements affect overall basin resilience to drought.
