Discussion of Lessons to be Learned from the 2017 Oroville Dam Spillway Incident
Moderated by John W France, P.E.

In its final report, the Independent Forensic Team (IFT) for the 2017 Oroville Dam spillway incident identified a number of lessons to be learned from the incident. This session will be a discussion of some of those lessons to be learned with a panel of regulators and dam owners. For each lesson to be discussed, John France, the leader of the IFT, will explain the team’s thoughts on that lesson, and then ask each panel member to comment. Questions will also be taken from the audience. Panel members will be:

•    Ted E. Craddock, P.E., or Joel Ledesma, California Department of Water Resources, O&M Division
