The Oroville Spillways – Overview and Instrumentation

Alec Naugle, Ross Steenson Erica Kalve

PRESENTATION:

On February 7, 2017, a hole formed in a portion of the concrete-lined spillway at Oroville Dam. Continued operation of the gated spillway caused additional erosion and damage to the concrete-lined spillway structure. This presentation will provide an overview of the spillway incident and the spillways recovery design and construction, including DWR’s first major implementation of real-time telemetered instrumentation to monitor changes in groundwater conditions and slope stability.
