About these readings
Readings come from USGS real-time monitoring stations — 67 sensors are currently reporting a water temperature in Washington. Each figure is a point measurement at one sensor, usually on a river or stream — it doesn’t describe a whole lake or shoreline, and coverage varies across the state. Data is provisional and can be revised by the USGS.
