A woman is in critical condition at Harborview Hospital after she fell off an inner tube while floating down the Green River with friends at Flaming Geyser State Park on Tuesday afternoon.

The woman and two friends were floating down the river when the group fell off of their tubes and were swept downstream, the King County Sheriff’s Office reported.

A woman in the group was able to safely escape the river but the other two, a male and a female, continued downstream. People who witnessed the incident called 911 around 2:45 p.m., and King County Fire District 44 (Mountain View Fire) and King County Sheriff’s personnel responded to the scene.

When rescue personnel arrived they could hear someone yelling for help near a bridge downriver from where the pair was last seen. Rescue crews were able to reach the pair and pull them out of the river. The woman was unconscious and was airlifted to Harborview in life-threatening condition.

In light of the warmer temperatures, King County officials are reminding the public of the dangers associated water recreation. Rivers are inherently dangerous. With winter’s heavy mountain snowpack much of the Cascade Range is beginning to melt. Rivers in King County are expected to have cold, fast flows throughout the summer.

Anyone swimming, rafting or tubing should wear a U.S. Coastguard-approved life jacket. Never float the river alone and always tell someone your route, and when and where you expect to put in and take out.
