The falls were well-documented by the Lewis and Clark Expedition; the portage around the falls was a significant event of the expedition and they discovered Westslope cutthroat trout at the falls, which was given the scientific name named "Salmo clarki lewisi" in honor of both leaders.
The city of Great Falls, Montana derives its name from the falls.
