2 Best Sights in The Columbia River Gorge, Oregon

President Franklin D. Roosevelt dedicated the first federal dam to span the Columbia in 1937. Its generators (visible from a balcony on a self-guided tour or up close during free guided tours offered daily in summer and on weekends the rest of the year) have a capacity of more than a million kilowatts, enough to supply power to more than 200,000 single-family homes. There's an extensive visitor center on Bradford Island, complete with underwater windows where gaggles of kids watch migrating salmon and steelhead as they struggle up fish ladders. The best viewing times are between April and October. In recent years the dwindling runs of wild Columbia salmon have made the dam a subject of much environmental controversy.

At this hydroelectric dam 50 miles east of the Bonneville Dam, you can tour a visitor center, which is located on the Oregon side of the river at Seufert Park, with surprisingly even-handed exhibits presenting differing perspectives on the Columbia River dams, with input from farmers, utility companies, environmentalists, and indigenous tribes. There's also a live feed of salmon and sturgeon scaling the fish ladder.
