Advanced Capabilities and Research

Federal Priority Streamgages (FPS) are automated stations that monitor water conditions in streams and rivers throughout the country. Originally established in 1999, these are important for meeting specific long-term needs of the Nation. The FPS Network was recently re-prioritized which resulted in size of the network increasing to nearly 12,400 locations.

The USGS groundwater Climate Response Network is a national network of wells selected to monitor natural groundwater-level conditions in unconfined or near-surface confined aquifers that are minimally affected by pumping or other human-induced stresses.

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.

The USGS National Water Availability Assessment consists of reports, which provide a scientific summary and interpretation of water quantity, quality and use, and the data companion, which delivers model-based estimates of water supply and demand.

Regional Water Availability Assessments are scientific assessments of water availability in different hydrologic regions across the Nation. They are designed to capture a range of conditions in major drivers of water availability.

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 National Water Availability Assessment Data Companion (NWDC) delivers model-based estimates of water supply and demand.

As of October 2024, the USGS Groundwater and Streamflow Information Program supports the collection and (or) delivery of both streamflow and water-level information at 8,705 sites and water-level information alone at 3,460 additional sites. The data are served online—most in near real-time—to meet many diverse needs including the protection of life, property, the environment, and our economy.

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.

Centennial Streamgages are USGS streamgages that have been in operation for more than 100 years.

The Willamette River Basin reflects the conflicting water demands between humans and ecosystems—particularly salmon— and the challenge resource managers face throughout the Pacific Northwest.
