Preparation under way for fish passage at Oregon’s 40-MW Foster hydropower plant

Divers from Vancouver-based Northwest Underwater Construction have been working on the face of Oregon’s Foster Dam in preparation for a new Oregon Department of Fish and Wildlife facility.

The underwater work is part of a project that will eventually see a new fish trap and haul facility built at the Foster Dam complex, which also includes a 40-MW powerhouse on the South Santiam River.

An official from project owner the U.S. Army Corps of Engineers’ Portland District says Northwest Underwater Construction divers have cleaned trashracks and prepared a plan to cover water outlet pipes once construction begins.

The new system replaces the current one, which was built in 1968. reported in August that the Corps’ Portland District awarded a US$18.6 million contract to Natt McDougall Co. to oversee the project.

Construction is expected to be completed by March 2014.
