The California Department of Water Resources stopped the spillway flow on Thursday morning to allow engineers to evaluate the integrity of the structure after water had been released at 20,000 cubic feet per second (cfs) through the night. There is no imminent or expected treat to public safety or the integrity of Oroville Dam at the Butte County site. After conferring with State and federal dam safety entitles, DWR decided to increase the release volume to 35,000 cfs to help operators absorb the inflow of the storm waters expected today and Friday. More erosion is also expected.
