King County Flood Warning Center: Heavy rainfall leads to potential minor flooding along White River


The King County Flood Warning Center has issued a Phase 2 flood alert for the White River below Mud Mountain Dam, with minor flooding possible – the result of steady rainfall across the region.


King County’s Flood Warning Center has issued a Phase 2 rsz_kcfcd_21flood alert for the White River, with possible minor flooding occurring below Mud Mountain Dam, after heavy rainfall brought rising water levels to streams and rivers across the county.

As of 2 p.m., flows on the White River below Mud Mountain Dam east of Enumclaw were recorded at 5,020 cubic feet per second (CFS), slightly higher than the Phase 2 flood alert threshold of 5,000 CFS. At these flows, some minor overbank flooding could be expected near the A-Street Bridge in Auburn, and near Government Canal and Butte Avenue in Pacific. High river flows could also be expected along the temporary flood protection barriers in Pacific.

The White River joins the Snoqualmie and Tolt rivers at Phase 2 flood alert levels, with minor flooding possible in low-lying areas along those rivers as well. Issaquah Creek reached a Phase 2 flood alert level early in the evening of Jan. 6, and flows have since receded along the creek.

King County flood patrol crews are continuing their field operations of checking conditions and reporting their findings to colleagues at the King County Flood Warning Center, which has been open since 6 p.m. on Thursday, Jan. 6 to coordinate the county’s response to this ongoing flood event.

During river flooding, 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.
