Water priorities for the Nation—U.S. Geological Survey Integrated Water Availability Assessments

Abstract

The United States faces growing challenges to its water supply, infrastructure, and aquatic ecosystems because of population growth, climate change, floods and droughts, and aging water delivery systems. To help address these challenges, the U.S. Geological Survey (USGS) Water Resources Mission Area has established new strategic priorities that capitalize on the operational and scientific strengths of the USGS to address these complex societal issues. The USGS Integrated Water Availability Assessment Program within the Water Resources Mission Area will provide nationally consistent assessments of water available for human and ecological needs and identify factors that limit water availability. Integrated Water Availability Assessments will assess current conditions, long-term trends, factors responsible for current conditions and observed trends, and provide forecasts of future changes at national and regional scales.
