One Dam Removal Project Ends, Another Begins

April 10th, 2017

WSC was recently named the construction management consultant for the largest dam removal project in the United States, the $450 million Klamath River Dam Removal Project, which involves the decommissioning of four hydroelectric dams and along a 373-mile stretch of the Klamath River in Southern Oregon and Northern California.

The non-profit Klamath River Renewal Corporation will oversee the project if it is approved by the Federal Energy Regulatory Commission (FERC). Iron Gate Dam, Copco No. 1 Dam, Copco No. 2 Dam, and J.C. Boyle Dam will be decommissioned, and there will be localized river restoration where the dams are deconstructed. For more information on the project visit www.klamathrenewal.org.

WSC will soon begin providing construction management support during the early stages of the project and throughout the physical removal of the dams, which is expected to begin in 2020.

WSC is a national leader in the field of dam removal and will bring the experience of serving as the program and construction management consultant on the largest dam removal in California, the $83 million Carmel River Reroute and San Clemente Dam Removal and River Restoration Project. That project is in the final closeout period and will serve as a model for future projects as other old dams reach the end of their useful lives and are torn down due to safety and environmental concerns.

The removal of San Clemente Dam, which was owned by California American Water Company, was the culmination of a massive public-private partnership which will result in approximately 25 miles of spawning and rearing habitat for endangered South-Central California Coast Steelhead Trout and improved habitat for threatened California Red-Legged Frogs. WSC will remain the construction management consultant during a 10-year period of monitoring and habitat establishment, which is already underway.

San Clemente Dam was removed in December 2015 and work continued into 2016 when the Old Carmel River Dam was removed and a stretch of the Carmel River was restored. Other key milestones in 2016 included : The removal of Sleepy Hollow Ford low water crossing and the construction its replacement, the 150-foot Sleepy Hollow Bridge; demolition of the Carmel Valley Filter Plant, water tanks, chlorine storage plant, and Dam Keeper’s House; and the completion of the Tularcitos High Road Access Route.

California American Water Company will donate 925 acres of land to the U.S. Bureau of Land Management for public use after the development of a long-term management plan.
