16 the Nisqually River will cause severe near record flooding from La Grande downstream through McKenna to the mouth. Deep and swift flood waters will inundate roads...farms...and residential areas...including the nursing home in McKenna. Erosion will likely cause severe damage. Flooding will occur all along the river including headwaters...tributaries...and other streams within and near the Nisqually River Basin.
