Check river conditions in the Flood Warning App
Flooding is King County's most common natural disaster, with the season starting in October. Prepare now to protect yourself and your loved ones.
Stay informed year-round with King County’s new Flood Warning App. The upgraded app offers reliable, real-time river levels and flood phases for seven rivers and Issaquah Creek. Access interactive graphs and information in multiple languages to help you stay ahead and act quickly.
The app shows current river flows, flood stage data and forecasts. Hydrographs make it easy to see several days of river data and forecasts. This app downloads data from the U.S. Geological Survey and National Weather Service and Northwest River Forecast Center about every 10 minutes. The app was developed by King County and is funded by the King County Flood Control District.
