The Jackson Creek Spillway in Amador County, California has been modified in response to issues raised during the Federal Energy Regulatory Commission (FERC) mandated 5-year safety inspections. The calculated factors of safety for the Jackson Creek Spillway, under the probable maximum flood (PMF) and maximum credible earthquake (MCE) loading conditions, were below levels considered acceptable by the FERC and modifications to the structure were required. Woodward-Clyde Consultants, under contract to the East Bay Municipal Utility District (EBMUD), designed the modifications and in the summer and fall of 1994 the modifications to the Jackson Creek Spillway were successfully constructed with both FERC and California Division of Safety of Dams (DSOD) approval. This paper will summarize the design and construction issues, and discuss the lessons learned during modification of this 67-year-old structure.
