NOTE: River forecasts for this location take into account past and future precipitation. The stages/flows that will occur may be different if future rainfall is different than forecast.

NOTE: Forecast river flows take into account forecasts of dam operations and are subject to change.

Reliability of the Forecast: Based on current and forecast river, weather and reservoir conditions

NOTE: Forecasts for the White River at Mud Mtn. Dam - Outflow are issued routinely year-round.

Flood Impacts & Photos Collapse
If you notice any errors in the below information, please contact our Webmaster
14000 the White River will cause major flooding above and below Mud Mountain Dam downstream to near Auburn. 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 to near Auburn. 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 to near Auburn. Deep and swift flood waters will inundate roads and surround and cut off access to some homes in the Red Creek area. Flood damages occur at the fish hatchery near the City of Enumclaw. 10000 cfs on the White river corresponds to a phase 4 flood in the King County flood system.
8000 the White River will spill over its banks below Mud Mountain Dam producing high water that will encroach on roads and residences, particularly in the Red Creek area. 8000 cfs on the White River is within phase 3 flood in the King County flood system.
