"The western branch of this river is much larger than the eastern, and after we passed the junction we found the river about one hundred yards in width, rapid and shoaly, but containing only a small quantity of timber. As captain Lewis was the first white man who visited its waters, captain Clarke gave it the name of Lewis's river."

"At its mouth Lewis's river is about two hundred and fifty yards wide, and its water is of a greenish blue colour."

"Sergeant Ordway and two men were also despatched to Lewis’s river, about half a day’s ride to the south, where we expect to obtain salmon, which are said to be very abundant at that place."
