River and stream flow monitoring
We maintain a network of stream-gaging stations that report streamflow conditions in rivers and streams across the state. The information is used to monitor flow conditions for water supplies for people and migrating fish, recreational activities and to develop strategies to respond to climate change. The data we collect are available to view and download.
Continuous data for rivers and streams
The Freshwater DataStream application contains nearly real-time data for our long-term monitoring program. Data show streamflows and some water quality parameters gathered by our automated stations. Freshwater DataStream shows continuous data from active monitoring stations. It also contains historical data records for discontinued stations.
Check out our Statewide Stream Summary Map to see nearly real-time summaries of streamflow conditions around the state. Color-coded dots indicate if today's flows are above or below normal for this time of year.
