The Bonneville lock was the first lock for the Cruise West Spirit of Discovery on its upstream voyage through the Columbia River Gorge, and the last lock on its downstream voyage to the Pacific Ocean at Astoria.
The small ship docked at the Visitor's Center, and we watched the migrating fish move past the underwater viewing windows and learned much about the Bonneville complex from its exhibits and the rangers. Our group also toured the outside areas and the powerhouse, where we saw the "fish-friendly" turbine. After the interesting tour, we went to Multnomah Falls.
