Condit

The Condit Hydroelectric Project was located on the White Salmon River in south-central Washington, approximately three river miles upstream from its confluence with the Columbia River. PacifiCorp agreed to decommission and remove the project dam and water conveyance system in accordance with the 1999 Condit Hydroelectric Project Settlement Agreement and the related Federal Energy Regulatory Commission (FERC) Surrender Order issued in December 2010.

Work began in June of 2011, the dam was breached on October 26, 2011, and dam removal was completed on September 14, 2012. The former reservoir area was revegetated in March 2013. 

Steps involved in decommissioning the Condit project included constructing new bridge piers for the Northwestern Lake Road bridge which provides public access across the White Salmon River, relocation of a City of White Salmon waterline and removing the dam, intake structure, wood stave flowline from dam to surge tank, surge tank, penstocks from surge tank to powerhouse, and powerhouse tailrace wall.

The powerhouse remains. The penstock entrances into the powerhouse turbines have been blocked as well as the exit to the tailrace. Environmentally sensitive materials such as hydraulic oils and batteries have been removed from the powerhouse.
