The King County Flood Warning Center has issued a Phase 2 flood alert for the White River below Mud Mountain Dam, with some minor flooding possible in low-lying areas near the river in Auburn and Pacific.
As of 2 p.m., the White River below Mud Mountain Dam was flowing at 5,000 cubic feet per second (CFS), which is the Phase 2 flood alert threshold.
At these flows, there is the potential for minor flooding along the White River near Auburn and Pacific, including upstream of the A Street Bridge in Auburn, and near Government Canal and Butte Avenue in Pacific. High flows are also possible along the temporary flood-protection barriers that have been erected along the White River in Pacific.
The Flood Warning Center opened at 3:30 p.m. on Monday, Jan. 6 to monitor rising river levels as a result of a strong winter storm that brought several inches of rainfall to parts of eastern King County. The Snoqualmie and Tolt rivers both reached Phase 3 flood alert levels as a result of the storm, with moderate flooding observed along those rivers.
Rivers across King County continue to run high, and Flood Warning Center employees will continue monitoring stream gauges and weather reports and provide updated information on river conditions as necessary. Real-time river level information is available online at kingcounty.gov/flood.
During river flooding events, King County serves as a clearinghouse for information on flood conditions, operating a recorded message center with continuous updates of river gauge readings and flood phases and other related information. Reach the Flood Warning Center at 206-296-8200 or 1-800-945-9263. Interpreter assistance in multiple languages is available.
