SACRAMENTO, Calif. - The Bureau of Reclamation has awarded a $11,141,820 construction contract for the Nimbus Dam Radial Gate Repair Phase III to Alltech Engineering Corp. of Mendota Heights, Minnesota. The dam is located near Sacramento, Calif.

The primary purpose of the project is to repair 14 spillway gates and construct a bulkhead storage facility by the end of fiscal year 2019. Over the five-year construction period, the project will include removing and disposing of the coating that potentially contains lead and other heavy metals and performing mechanical repairs on the nearly 70-year-old gates. The contract also calls for making concrete repairs to the dam’s spillway and piers.

Nimbus Dam was constructed in 1956. The original steel wire ropes were replaced with stainless steel wire ropes in the 1980s, but other than normal maintenance, no major work has been done to the gates since the dam began operations. Four of the dam’s 18 gates were repaired in previous phases. This will be the final contract for the remaining 14 gates.

“This construction project will help bring Nimbus Dam – a key feature of the Central Valley Project ­­­­– up to date,” said Acting Reclamation Commissioner Lowell Pimley “It will ensure the Nimbus Dam facility continues to operate at full capacity, while protecting and safeguarding environmental conservation and water-related recreational activities.”

Nimbus Dam is located about seven miles downstream of Folsom Reservoir and impounds Lake Natoma, a regulating reservoir for water releases out of Folsom Dam/Reservoir.
