Willamette Falls Locks

Clackamas County · Oregon

The board says the locks are still in use. They have not been since November 17, 2011, when the Corps of Engineers closed them over safety concerns. They were built from 1870 to 1872 to break a monopoly, the People's Transportation Company's control of every portage of freight around the falls, and passage through them was free. In 2019 the Corps decided to hand them off. The Willamette Falls Locks Authority, chartered by the legislature in 2021, is to take ownership once seismic repairs begun in 2023 are finished; the transfer was expected in 2026.

What the plaque says

Oregon History Willamette Falls Locks — still in use below this point — were opened on New Years Day, 1873, when the steamer Maria Wilkins became the first vessel to navigate up the west end of Willamette Falls. Farming and shipping interests had long sought to eliminate expensive portages around this age-old bar to navigation 26 miles above the mouth of the river. The initial project was completed by the Willamette Falls Canal and Locks Company with a partial state subsidy at a cost of $450,000. Five locks-including a canal basin and guard lock at the upper end provide a total lift of 50.2 ft. Carved from native rock and finished with masonry. The locks have concrete sills and are lined with timbers.
