10500 the Tolt River will cause severe flooding. Dangerously deep and quick flood waters will cover roads and driveways...with some homes flooded. The river will likely overtop some levees. Erosion could cause serious damage and channel changes may occur. Flooding will occur all along the river including headwaters...tributaries...and other streams within and near the Tolt River Basin. This river level on the Tolt corresponds to a phase 4 flood in the King County flood system.
8500 the Tolt River will cause major flooding. Deep and quick flood waters will cover roads and driveways...cutting off access to many homes. Levees may overtop and channel changes may occur.
