The Willamette Falls are created where the Willamette River at Oregon City spills 40 feet over a basaltic ridge. The locks were built in the early 1870s to move river traffic around the falls. They are no longer operational and have been designated as a National Treasure by the National Trust for Historic Preservation. The locks are closed to public access but visitors can still admire the falls and the locks from a distance, with especially good views from West Bridge Park in West Linn.
