The National Streamflow Information Program

MISSION

Provide the streamflow information and understanding required to meet local, State, regional, and national needs.

Goals


What is streamflow?

Streamflow is the amount of water moving in a stream or river past a given point through time and is typically reported in cubic feet per second, or million gallons per day. You can see the amount of water currently flowing in a river near where you live or elsewhere in the Nation by going to http://water.usgs.gov/nwis/rt.

The USGS currently operates about 7,500 streamgages nationwide. Streamgages are the monitoring tools used to track the movement of water in streams and rivers.

“Nationwide, the benefits........greatly exceed the cost of collecting the data through NSIP.”

National Hydrologic Warning Council, 2006


When fully implemented, NSIP will provide Nation-wide streamflow information and understanding needed by a wide range of users. See http://water.usgs.gov/nsip/
