Green River expected to rise to Phase III flood alert level with dam’s release

The swollen Green River is at a Phase II flood alert level, according to the King County Flood Warning Center.

The swollen Green River is at a Phase II flood alert level, according to the King County Flood Warning Center.

The river was flowing at 8,530 cubic feet per second at the Auburn gage as of 1:30 p.m. Friday. However, flows on the Green were expected to rise later Friday to a Phase III flood alert level as water releases from Howard Hanson Dam in the upper Green River watershed will push the river higher.

Only minor flooding is expected in the rural areas of the Green River Valley without levees upstream of Auburn. The increased flows also bring the potential for overtopping along Southeast Green Valley Road and West Valley Road.

Flood Warning Center staff will monitor stream gages and weather reports, and will provide updated information on river conditions as necessary. Real-time river level information is available online at www.kingcounty.gov/flood.

Updated information on flooding will also be posted on the King County website at www.kingcounty.gov, or via RPIN, the area’s regional website at www.rpin.org. A recorded flood-information hotline is also updated each hour for citizens wanting information in flood areas. The number is 206-296-8200 or 1-800-945-9263.

Citizens who need help interpreting flood information should call 206-296-4535 or 1-800-768-7932. Problems on county maintained roads can be reported by calling 206-296-8100 or 1-800-KC-ROADS.
