A Bonneville Dam fish count is available on the official Idaho Fish and Game website. The count includes hatchery origin and wild fish. While the Bonneville Dam is in the state of Oregon, most salmon bound for Idaho cross the dam between July and October. The list provides a daily count, total to date and five-year average total count to date.
The Bonneville Lock and Dam is the location of the Bonneville Fish Hatchery, an operation of Oregon Fish and Wildlife. The Bonneville Fish Hatchery is a coho salmon and chinook salmon hatchery with display ponds to feed large rainbow trout and view white sturgeon adults that measure more than 6 feet in length. The Bonneville Hatchery has a diverse fish production program, including adult collection, spawning, egg incubation and rearing.
Interpretive displays at the Bonneville Dam discuss the movement and lives of the salmon and other fish that live in the Columbia River. There is a viewing area at the dam where visitors may watch spawning activities in the fall. The dam has two powerhouses and a spillway that provide hydropower to the Pacific Northwest. The Bonneville Lock and Dam is approximately 40 miles east of Portland, Oregon, at the border of Washington state, and is 145 river miles from the mouth of the Columbia River.
