| Abstract | Long Description |
PacifiCorp proposes to remove the Condit Hydroelectric Project on the White Salmon River in accordance with the Condit Hydroelectric Project Settlement Agreement, as amended in 2005. Removal of the project would enable the river and watershed to return to the conditions of a freeflowing river. Originally completed in 1913, Condit Dam has since accumulated sediment and blocked fish passage. Removing the dam is expected to provide access to as much as 32.4 miles of river and tributary habitat for anadromous steelhead and salmon, and restore connectivity to foraging, spawning, rearing, and overwintering habitat for bull trout in the lower White Salmon River. The removal also would restore natural bed load movement processes in the river. Combined with a stable and natural flow regime, dam removal would result in increased salmonid (steelhead, salmon, and bull trout) production potential. |
