This is an animation showing the changing conditions of USGS streamgages for Water Year 2018 (October 1, 2017 to September 30, 2018). The conditions shown range from the driest condition seen at a gage to the wettest.
Get the facts and figures about the USGS Streamgaging Network, one of the largest streamgaging enterprises in the world!
All numbers below are for 2023.
National Streamgage Network
11,885 Streamgages
- 8,635 monitor streamflow and water level year-round
- 3,250 only record water level or operate less than year-round
- More than 80,000 streamflow measurements made by hydrographers
- Centennial Streamgages - have more than 100 years of records
- CY 2024 - 900
- CY 2023 - 844
Federal Priority Streamgages
3,438 active streamgages
- 1,318 eligible locations inactive due to lack of funding
Funding
Approximately $200 million
- $58 million from Federal appropriations
- Approximately $162 million from nearly 1,500 partners
Water Data Delivery
In FY23, 1.48 billion of the 2.21 billion requests for USGS water information were for streamflow data
- Nearly 98% of requests fulfilled through web services

National Water Dashboard (NWD)
The National Water Dashboard (NWD) is a mobile, interactive tool that provides real-time information on water levels, weather, and flood forecasts - all in one place on a computer, smartphone, or other mobile device. The NWD presents real-time stream, lake and reservoir, precipitation, and groundwater data from more than 13,500 USGS observation stations across the country.
