Willamette Falls Locks, Navigation lock system at West Linn and Oregon City, United States.

The Willamette Falls Locks are a four-chamber lock system on the Willamette River at West Linn, Oregon, with seven gates and chambers measuring 210 by 40 feet (64 by 12 m). The complex stretches 3,565 feet (1,087 m) and lifts vessels up to 50 feet (15 m) to bypass Willamette Falls and the T.W. Sullivan Dam. It can accommodate boats up to 75 feet (23 m) long.

The Willamette Falls Canal and Locks Company was incorporated on September 14, 1868, to break the People's Transportation Company's grip on river freight. The Oregon legislature subsidized the work, and the canal and locks were built from 1870 to 1872, opening in 1873. The Army Corps of Engineers later operated them until closure in 2011; repair work began in 2023.

The Willamette Falls Canal and Locks Company was incorporated on September 14, 1868, by Clackamas County promoters and steamboat captain Ephraim W.

Tolls were capped at fifty cents per ton of freight and ten cents per passenger.

The site is visible from outside and accessible to visitors even though operations are currently halted. Keep in mind that major renovation work is underway, with the facility expected to resume normal operations in 2026.
