2006 Snoqualmie flooding by T Sayles

The King County Flood Warning Center opened this morning at 8:30 am to keep an eye on rising flows in on the Snoqualmie and Tolt rivers due to heavy rainful.

Per the County’s press release, at 9 am the sum of the forks of the Snoqualmie River was 13,428 cubic feet per second (cfs), which is above the threshold for a Phase II flood alert level. This means that minor flooding might affect the agricultural areas in the Snoqualmie Valley.

The Tolt River was flowing at 2,920 cfs at 9 a.m., which is a Phase II flood alert level. Some slight flooding could happen in low-lying areas along the Tolt River.

Flood warning staff monitor the river levels until threat of flooding has passed: for real time river levels, check out their flood page.
