To manage our water resources effectively, we need to understand how much water is available and its usefulness. The USGS monitors the nation’s water resources through various national observing networks that use a range of technologies and methods to assess real-time water conditions and predict future changes in water availability for human and ecological uses.

Understanding the quality of U.S. streams, rivers, and groundwater requires consistent data collection and analysis over decades for proper context of current conditions. The USGS collects nationally standardized data and information as part of the National Water Quality Network (NWQN). The NQWN is made up of sites across the Nation where USGS scientists regularly measure water-quality conditions.

The USGS Water Resources Mission Area is assessing how much water is available for human and ecological needs in the United States and identifying where and when the Nation may have challenges meeting its demand for water.

The USGS Integrated Water Prediction science program is focused on developing and improving model code, workflows, and applications of core water availability components at a national extent.

Regional Water Availability Assessments are scientific assessments of water availability in different hydrologic regions across the Nation. In the Upper Colorado River Basin, the USGS will conduct a focused assessment of how snowpack and snowmelt influence hydrology and water quality, and an integrated and comprehensive assessment of multiple water quantity, quality and use factors.

Regional Water Availability Assessments are scientific assessments of water availability in different hydrologic regions across the Nation. In the Delaware River Basin, the USGS will conduct a focused assessment of increasing freshwater salinity and an integrated and comprehensive assessment of multiple water quantity, quality and use factors.
