Webinar: Human Factors in the Oroville Dam Spillway Incident

This event qualifies for 2 PDH

Oroville Dam is the tallest dam in the United States. On February 7, 2017, a section of the concrete chute slab of the service spillway failed during spillway discharge, and several days later the emergency spillway was activated for the first time in the half-century history of the dam, resulting in rapid and severe erosion of the hillside below the emergency spillway weir, and prompting precautionary evacuation of nearly 190,000 downstream residents. The Federal Energy Regulatory Commission mandated a forensic investigation of the incident. This webinar will serve as a "Part 2" continuation of a prior ASDSO webinar (Findings of the Oroville Dam Spillway Forensic Investigation) which presented an overview of the findings of the forensic investigation by the six-person Independent Forensic Team, and will expand on the prior webinar's discussion of human, organizational, and industry factors contributing to the incident, beginning with the design of the project and continuing until the decision-making during the incident response. Ample time will be allowed for questions from attendees.


4 takeaways attendees can expect from this webinar:


  • Understand the human factors framework used for the forensic investigation.
  • Learn about the challenges and process used for investigation of human factors.
  • Understand the human factors, including organizational and industry factors, contributing to the incident.
  • Learn about the suggested lessons to be learned identified by the forensic investigation team.
