DWR Expands On Response To Spillway Forensic Report

The state Department of Water Resources has beefed up its response to the independent forensic report on what caused the Oroville Dam spillway failure last year. The report, released on Jan. 5, described how insufficient maintenance and repairs and faulty original design allowed water to seep through the spillway’s cracks and joints. It also blamed “long-term systemic failure” on the part of DWR, regulators and the dam safety industry at large.
