Using River and Stream Flow Data
The map-based application, the Flow Monitoring Network, can provide nearly real-time data about streamflow and water quality for many rivers and streams in Washington State.
Find streamflow data from a map
The short video below shows how to navigate to information from nearly real-time river and stream monitoring stations around the state. Click on the map to the right to go straight to the map-based database.
Find streamflow data by Water Resource Inventory Area
If you know the Water Resources Inventory Area or WRIA for your river or stream of interest, you can find data for monitoring stations in that area using the drop-down menu below. A WRIA is the area included in one watershed and that is inside of Washington State boundaries.
Select a Washington Watershed by Zip Code can help you find your WRIA name and number, as can this WRIA map. Once you know, use the drop-down menu below to go to your watershed's first station page in the Flow Monitoring Network application. From there, the listing under the map on the right-hand side of the page contains the stations in that WRIA.
