"DWR engineers and geologists continue to assess the concrete erosion on the Oroville Dam Spillway"
The California Department of Water Resources has suspended flows from the Oroville Dam spillway after a concrete section eroded on the middle section of the spillway. There is no anticipated threat to the dam or the public. DWR engineers are assessing the options to repair the spillway and control the reservoir water level. The Butte County facility is the tallest dam in the United States at 770 feet and is a key part of the State Water Project. Photo taken February 7, 2017.
