Groundwater and Streamflow Information Program
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 stakeholders across the United States. In 2018, the USGS began piloting the Nation’s Next Generation Water Observing System (NGWOS) that will provide high-fidelity, real-time data on water quantity and quality.
