Flood Impacts & Photos Collapse

14000 the White River will cause major flooding above and below Mud Mountain Dam downstream. Deep and swift flood waters will inundate roads and residential areas. Damage due to erosion is likely. Flooding will occur all along the river including headwaters...tributaries...and other streams within and near the White River Basin. 14000 cfs on the White River corresponds to above phase 4 flood in the King County flood system.
12000 the White River will cause flooding above and below Mud Mountain Dam downstream. Deep and swift flood waters will inundate roads and residential areas. Damage due to erosion is likely. 12000 cfs on the White River corresponds to a phase 4 flood in the King County flood system.
10000 the White River will flood areas above and below Mud Mountain Dam downstream. Deep and swift flood waters will inundate roads and surround and cut off access to some homes in the city of Pacific and the Red Creek area. 10000 cfs on the White river corresponds to a phase 3 flood in the King County flood system.
8000 the White River will spill over its banks below Mud Mountain Dam producing high water...overtopped roads...and encroaching on residences. Flood waters will threaten city of Pacific and the Red Creek area. 8000 cfs on the White River corresponds to a phase 2 flood in the King County flood system.
