Canadian Dam Association Bulletin - Winter 2019 - 10

Looking beyond Oroville: Where to from here?
By Stephen Rigbey, P.Eng., SJR Consulting
Member of Oroville Independent Forensics Team (IFT)

This article is based on the invited lecture given by Mr. Rigbey at the 2018 CDA Conference.

T

he Independent Forensics Team
(IFT) report, published around
10 months after the Oroville
spillway failure in February 2017,
concluded that the failure involved

a complicated interplay between
physical, organizational and human
factors that spanned decades. There
was not one simple failure mode or
linear progression of events that led

to the spillway failure and subsequent
evacuation of 188,000 downstream
residents; however, there were simple tell-tale signs of major unresolved
issues that contributed to the failure
