Welcome to the National Streamflow Information Program (NSIP) web page. The U.S. Geological Survey operates and maintains approximately 7,300 streamgages which provide long-term, accurate, and unbiased information that meets the needs of many diverse users. Streamgaging under the National Streamflow Information Program (NSIP) provides the Nation with streamflow information to help protect life and property and manage our water resources. The streamgaging network is supported by four funding sources: the USGS Cooperative Water Program, the USGS NSIP, other Federal agencies (primarily the Corps of Engineers and Bureau of Reclamation) and 800 State and local funding partners.
The mission of NSIP is to provide the streamflow information and understanding required to meet local, State, regional, and national needs. Streamgages are the monitoring tools used to track the flux of water and associated components in streams and rivers. Streamflow data from these streamgages are used for planning and decisions related to agriculture, industry, water supplies, navigation, riverine and riparian habitat, and flood hazard identification. The plan for 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 needs of streamflow information while ensuring that local needs continue to be met.
The USGS National Streamflow Information Program (NSIP) is designed with five components, one of which is to provide a "backbone" or core of streamgages that are of such critical importance to national streamgflow information needs that their operation should be assured with Federal funds. NSIP was created in response to Congressional and stakeholder concerns about (1) a loss of streamgages, (2) a disproportionate loss of streamgages with a long period of record, (3) the inability of the USGS to continue operating high-priority streamgages when partners discontinue funding and (4) the increasing demand for streamflow information due to new resource-management issues and new data-delivery capabilities.
Notice: Threatened Streamgages
The following streamgages have been discontinued or are being considered for discontinuation or for conversion from continuous record discharge to stage-only stations. The primary reason for these actions is the lack of funding to support the continued operation of the streamgages. Funds for these streamgages are from the U.S. Geological Survey and other Federal, State, Tribal, and local agencies. For those streamgages that have already been discontinued, extensive efforts were made to find another funding source, however, when no funding was made available the streamgages had to be discontinued. For those streamgages at risk for discontinuation, the current funding source has indicated that it can no longer fund the streamgage. Efforts are currently underway to identify another funding source for the operation of these streamgages; however, if no funding is identified, then these streamgages will have to be discontinued also. If you have questions about the US Geological Survey National Streamflow Information Program in general please contact Mike Norris (603-226-7847; mnorris@usgs.gov) or Steve Blanchard (703-648-5629; sfblanch@usgs.gov). If you have questions about specific streamgages in the list below, please contact the individual identified for each State.
