Oroville Dam Spillway Presentation
By Taki Chrysovergis, M.S., P.E.
The Orange County Geo-Institute and CalGeo co-hosted a dinner meeting at The Hacienda in Santa Ana, California on March 1, 2018, where Ms. Holly Nichols, Senior Engineering Geologist for the California Department of Water Resources, presented on the Oroville Spillway. The event was attended by more than 90 individuals from various affiliations, including, ASCE, Geo-Institute, and CalGeo members.
During the presentation, Ms. Nichols covered the geologic conditions at the site prior to construction, the geologic exploration completed since the spillway failure, and the spillway reconstruction design, construction, and status. Also included in the presentation, were photos and videos taken of the damaged concrete spillway, as well as during use of the emergency spillway. We would like to give a special thanks to Hayward Baker for their continued support.
