Celilo Falls Portage is a High Potential Historic Site on the Lewis and Clark National Historic Trail.

On October 22, 1805, the expedition reached Celilo Falls, where the river “divided into Several narrow chanels which pass through a hard black rock forming Islands of rocks at this Stage of the water, on those Is­lands of rocks [were] great numbers of Stacks of pounded Salmon.” A social and commercial locus for tribes along the Columbia River, Celilo Falls also presented a defacto boundary between Shahaptian languages (extending eastward to the Rocky Mountains) and Chinookan languages (extending westward to the Pacific Ocean). There were 17 lodges above the falls and five more below. Lewis and Clark determined a portage route “on the Stard. Side, and the distance 1200 yards one third of the way on a rock, about 200 yards over a loose Sand collected in a hollar blown by the winds from the bottoms below which was disagreeable to pass, as it was Steep and loose.” They received a great deal of assistance from the villagers, including the use of their horses. The Corps camped two nights on the north bank below the falls, “close under a high range of clifts of rocks, where the body of the River beat against it and formed a verry large eddy.” The return portage was made on April 21, 1806.

Over the years, Celilo Falls has been impacted by infrastructure developments such as a canal, railroad bridge, transmission lines, and inundation from the Dalles Dam. Even so, the portage route on the Wash­ington side of the river remains intact and above water. On-site access is restricted, but nearby Celilo Park provides public viewing and interpretation of the area from the Oregon side of the river.
