Forensic Team

The BOC described above should not be confused with the forensic analysis team, which has been engaged to determine the cause of the Oroville spillway incident. To provide for an independent review, DWR contacted the Association of State Dams Safety Officials and the United States Society of Dams to propose a team that can conduct a forensic evaluation. The six members of the forensic team were identified on March 15.

The forensic team is charged with determining the root cause of the spillway incident, as well as any other contributing causes. These factors may include operational, structural, geologic, and/or management causes. Preliminary findings were released on May 5 listing 24 physical factors that potentially may have contributed to the main flood control spillway damage and four physical factors that may have contributed to the emergency spillway damage. These preliminary findings and forthcoming findings will be shared with the BOC as it advises DWR on work to recover spillway function.
