History of the Expedition Under the Command of Captains Lewis and Clark: To the Sources of the Missouri, Thence Across the Rocky Mountains and Down the River Columbia to the Pacific Ocean
by Meriwether Lewis, William Clark"A short distance above this inlet a considerable river empties itself from the north side of the Columbia. Its name is Chawahnahiooks. It is about one hundred and fifty yards wide, and at present discharges a large body of water, though the Indians assure us that at a short distance above its mouth, the navigation is obstructed by falls and rapids."
