I encourage you to explore our website—it’s your doorway to a wide variety of USGS information and tools related to the monitoring of our Nation’s aquifers, streams, rivers, lakes, reservoirs, coastlines and precipitation. Since 1879, USGS scientists have been collecting, interpreting and providing groundwater and surface-water data in key areas of our Nation to help drive our economy and protect and conserve our precious natural resources. The Groundwater and Streamflow Information Program (GWSIP) serves as the national source of impartial, timely, rigorous and relevant data for short- and long-term water decisions by local, State, Tribal, regional and national stakeholders. 

Here you’ll find information on the Federal Priority Streamgage (FPS) program, Next-Generation Water Observing System (NGWOS), National Streamflow Network (NSN), National Groundwater Monitoring Network (NGWMN), Climate Response Network (CRN), Cooperative Matching Funds (CMF) and additional cooperative programs for special topics such as flood inundation mapping, StreamStats, and water hazards. The website provides easy access to databases, interactive tools, interpretive reports, photos, videos, maps, and more. If you’re interested in current or historic information about our Nation’s groundwater, streams, rivers, lakes, reservoirs, or precipitation, or perhaps in learning how our coastlines are impacted by hurricanes, nor’easters or tsunamis, you’ve come to the right place.

Thank you for your interest in the USGS and science we provide the Nation. Please don’t hesitate to contact me directly to learn more about the work we do, communicate your information needs, or connect with our scientists.
