Emergency News

Any of you who are in Oroville or south or west of it prepare for an emergency and please help neighbors who have limited resources. Water coming into Oroville Reservoir is so massive and the spillway so damaged that it will be forced out the so-called emergency spillway tonight, which has never been tried before (down a hillside of trees, no cement).  Hours ago the inflow was approximately 185,000 cfs, and outflows 41,602 cfs. Even with the storm winding down, the warm temperatures will melt significant snow. Below are phone numbers and web sites of county offices of emergency services.
