Bonneville Lock and Dam, a National Historic Landmark since 1987, spans across three islands (Cascades Island, Bradford Island, Robins Island) along Columbia River Gorge National Scenic Area at the state borders of Oregon and Washington. The dam owned by US Army Corps of Engineers is about 40mi (64km) upstream from Portland, Oregon. To cope with fish migration problems, the dam features fish ladders to help native salmon and steelhead get past the dam on their journey upstream to spawn. Fish hatchery is a popular tourist attraction during spawning season. There are three visitor info centers: Navigation Lock Visitor Area (Robins Island), Bradford Island Visitor Center, and Washington Visitor Complex (Cascades Island). The first two centers are in Oregon. Admissions to exhibits and parking are free at the visitors centers.
