Time: 8:00 AM- 5:00 PM

Facility: 136-MW Merwin Dam, 240-MW Swift Dam

Cost: TBA

The 46-MW T.W. Sullivan powerhouse, on the Willamette River in Willamette Falls, was built in 1895 and contains 13 turbine-generator units. The facility operates as run-of-river and contains a flow-control structure to help pass juvenile salmonids. T.W. Sullivan was inducted into Hydro Review's Hydro Hall of Fame in 1995 and was certified by the Low Impact Hydropower Institute in 2008.

Portland General Electric Tour

Date: Monday, July 13, 2015

Time: 8:30 AM- 4:30 PM

Facility: 25-MW River Mill, 46-MW Faraday, 58-MW North Fork

Cost: TBA

This tour features three of Portland General Electric's hydro projects in its Clackamas Project on the Clackamas River. In total, this project consists of eight dams, seven reservoirs and four powerhouses. The project features the longest operating fish ladder in the world, at 1.9 miles in length, running from the Faraday Diversion Dam to above North Fork Dam.

The 25-MW River Mill facility features the only surviving Ambursen-type dam west of the Mississippi River. It is listed on the National Register of Historic Places. The 46-MW Faraday project, the oldest of the three and the first hydro facility built on the Clackamas River, was completed in 1911. It was unique for its time in that a diversion dam was built to convey water through a canal to a man-made lake. A new surface collector for salmon is expected to be floated into place at the 58-MW North Fork facility about the time this tour is going on! This collector will augment earlier work to construct an adult fish sorting facility at the dam, which was completed in 2012.

Half-Day Tour

Date: Tuesday, July 14, 2015

Time: 8:30 AM- 1:00 PM

Facility: 1,077-MW Bonneville

Cost: TBA

This tour features the 1,050-MW Bonneville hydropower facility, the last dam on the Columbia River before it enters the Pacific Ocean. The first powerhouse, spillway and original navigation lock were completed in 1938 to improve navigation on the river and provide hydropower to the Pacific Northwest. A second powerhouse was completed in 1981 and a larger navigation lock in 1993.

The Bonneville First Powerhouse, which contains 11 turbine-generator units, is currently undergoing a rehabilitation that includes new turbine guide bearings, replacement main unit circuit breakers and instrument transformers, turbine repair work and much more.

The dam features fish ladders that provide an elevation gain of 60 feet and are used to transport returning adult chinook salmon, coho salmon, sockeye salmon, steelhead trout, American shad and lamprey to their spawning grounds.
