The Willamette Falls is a natural waterfall on the Willamette River between Oregon City and West Linn, Oregon, in the United States. It is the largest waterfall in the Northwestern United States by volume, and the seventeenth widest in the world.[1] Horseshoe in shape, it is 1,500 feet (460 m) wide and 40 feet (12 m) high with a flow of 30,849 cu ft/s (874 m³/s), located 26 miles (42 km) upriver from the Willamette's mouth. Willamette Falls is a culturally significant site for many tribal communities in the region.
Opened in 1873 and closed since 2011, the Willamette Falls Locks allowed boat traffic on the Willamette to pass into the main Willamette Valley.
