USGS National Streamflow Information Program (NSIP)

Welcome to the U.S. Geological Survey's National Streamflow Information Program (NSIP) web page. The mission of the NSIP is to provide streamflow information and the understanding required to meet local, State, regional, and national needs. The NSIP was developed to provide a National perspective, guidance, planning, and leadership to the streamgaging activities of the USGS. To provide streamflow information to meet national needs, the information obtained from these streamgages needs to be consistent, obtained using standard techniques and technology, and be subject to the same quality assurance and quality control. The NSIP plan provides for a unified network to meet National, regional, and local needs of streamflow information. The NSIP is designed with five goals, one of which is to provide a "backbone" or core streamgage network that are critical to national streamflow information needs and that would be funded totally with Federal funds. The USGS streamgaging network is currently funded in partnership with over 850 Federal, State, and local agencies.
