Below are other science projects associated with the USGS streamgaging network.
USGS National Streamgaging Network
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.
Federal Priority Streamgages (FPS)
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.
Rapid Deployment Gages (RDGs)
Rapid Deployment Gages (RDGs) are fully-functional streamgages designed to be deployed quickly and temporarily to measure and transmit stream stage data in emergency situations.
Streamgaging Basics
Information on the flow of rivers and streams is a vital national asset that safeguards lives, protects property, and ensures adequate water supplies for the future. The USGS operates a network of more than 13,500 streamgages nationwide that provide streamflow information for a wide variety of uses including flood prediction, water management and allocation, engineering design, research, operation...
Surge, Wave, and Tide Hydrologic (SWaTH) Network in Maryland, Delaware, and the District of Columbia
Many U.S. Geological Survey Water Science Centers have responsibilities for coastal regions within their mission areas. The integrated Surge, Wave, and Tide Hydrologic (SWaTH) Network has been developed in the wake of Hurricane Sandy to support model development and verification for coastal regions, detection of hydrologic trends, and early warning of hydrologic hazards in the northeast from...
