In January KOMO News reported on the Issaquah Creek flooding when,  “residents in Issaquah worked through the night early Friday to grab sandbags and place them to prevent waters from Issaquah Creek from flooding their homes and property.

Many of the city’s residents were worried that they would awaken to homes filled with waters as city officials warned that flooding could be as bad as flooding from 2020, when rising floodwaters from Issaquah Creek led to a phase 4 designation.”

From the City of Issaquah Government website: “To see more data of the upstream gauge in Hobart, visit the USGS website. This external site, however, is only updated once an hour. Using this data, King County also issues flood alerts by phone, text or e-mail.

The National Weather Service also broadcasts flood warnings for Issaquah Creek (along with other rivers in the region) based on its forecasts and/or observations at the downstream gauge near Lake Sammamish State Park. For forecast information, visit the National Weather Service National Oceanic and Atmospheric Administration.

You can register to receive updates from the King County Flood Alert system. Automated alerts are one of many ways to help protect your home, family, or business during a flood.
