Willamette Falls Locks

Willamette Falls Locks comprise four chambers equipped with seven gates designed to pass vessels up to 75 feet in length. The facility was constructed through solid rock to allow boats to bypass the natural 40-foot waterfall at this location.

Construction took place between 1871 and 1873, solving a major barrier to transportation in the region. This early engineering project improved boat traffic both upstream and downstream, helping to support commerce throughout Oregon.

The locks hold importance in Oregon's engineering story and represent a significant technical accomplishment. They stand as a tangible reminder of how communities once depended on waterways for moving goods and connecting regions.

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.

The facility stands as the oldest multi-chamber bypass canal built for commercial shipping in the country, with its chambers carved directly from bedrock. This underground approach was a bold engineering innovation that allowed boats to navigate around the falls without a separate waterway.
