Description:
The Columbia River is the largest river in the Pacific Northwest Region of North America. The river is 2,000 km long and its drainage basin is roughly the surface area of France.  By volume, the Columbia River is the fourth largest river in the United States and has the most flow of any North American river draining into the Pacific Ocean, providing an opportunity for hydroelectric generation.  The 14 hydroelectric dams on the main stem of the Columbia and many more on its tributaries produce more than 44% of the hydroelectric generation of the U.S.  Construction of Bonneville Dam, 40 miles east of Portland, Oregon, began in 1934.

Bonneville Dam is a concrete, gravity run-of-the-river hydroelectric dam with a height of 60 m and a length of 820 m.  Throughout the dam’s existence, passage facilities have been built and improved, as fishery scientists’ knowledge of the impacts of the dam upon migratory fish and potential remedies evolved.  This tour is an outstanding opportunity to learn how the U.S. Army Corps of Engineers and their partners provide upstream and downstream passage for migratory fish.  We will tour three sections of the dam; the Washington shore fish ladder, adult fish facility, and smolt monitoring facility.

Washington Shore Fish Ladder: Powerhouse 2 is located on the Washington State side of Bonneville Dam.  A large amount of the river flow passes through Powerhouse 2.  The higher flow attracts fish toward the Washington Shore fish ladders.

Adult Fish Facility: Attached to the Washington Shore fish ladder, this facility allows sampling of adult salmon and steelhead as they migrate upstream.  Staff members weigh, measure, and determine the age of the fish.  Collected data are used in fish passage studies and for fisheries management.

Smolt Monitoring Facility: Operated by the Pacific States Marine Fisheries Commission, researchers at the Smolt Monitoring Facility sample outmigrating smolts to determine age, species, size and condition – including length and weight. This information is published and helps fish managers understand the timing and characteristics of outmigrating fish – and helps forecast adult salmon returns. Smolt monitoring also helps identify any problems occurring in the juvenile bypass system, allowing a fast resolution of any issues.

Other tour and discussion topics include passage accommodations for lamprey and aquatic invasive species impacts upon passage, monitoring, and control.
