Once complete, the rehabilitated Lost Creek Dam is estimated to withstand potential floods and earthquakes for another century.
Granite Construction Incorporated announced July 27 it has been awarded a $20 million contract by the South Feather Water & Power Agency for the Lost Creek Dam Crest Modification Project in Strawberry Valley, CA. The contract will be included in Granite's second quarter 2017 backlog.
Scope of work includes increasing the dam spillway openings, raising the crest outside of the spill section, reinforcing the downstream face, protecting the plunge pool area to prevent scouring of the foundation material, and replacing the dam crossing road. Due to the remote area of the dam, all concrete materials will be batched on-site. Once complete, the rehabilitated dam is estimated to withstand potential floods and earthquakes for another century.
Work began in spring 2017 and is scheduled to be complete by fall 2018.
