About Streamflow Data for Washington
Streamflow data is collected continuously by USGS monitoring stations positioned at key points along rivers and streams across Washington. Each station measures water level (stage) and calculates flow rate (discharge) in cubic feet per second (cfs), providing a real-time picture of river conditions throughout the state.
What's the Flow? aggregates this data into an easy-to-read format, allowing you to quickly assess current conditions, compare flow rates to historical median flows, and identify rivers running significantly above or below normal levels.
