Check current river conditions

The King County Flood Warning App helps you stay informed about conditions on seven rivers and Issaquah Creek. Launch the app to view:
  • Current river conditions
  • Forecasts
  • Interactive graphs
  • Information in many languages through Google Translate

You can also install the app to use on your computer or mobile devices. The application downloads data from the U.S. Geological Survey, National Weather Service, and Northwest River Forecast Center about every 10 minutes. The app was funded by the King County Flood Control District and developed by King County.
