Reply to comment by AdmiralVernon in When this bridge in Fort Benton, Montana, USA was built 1888 it was required to have a swing span to allow steamboats to navigate. It was considered the furthest navigable point on Earth, more than 2,700 miles from the Gulf of Mexico. by triviafrenzy
in 1848 which predates op and fort benton in 1880. i'd still say that the south branch chicago river could have been navigable by smaller craft. but maybe not large steam boats.

Not to sound too obtuse, but how would you know that at all?

if indians could do it in canoes then so could pelt traders.

Doesn't matter if it's navigable if you couldn't get to it from the Illinois river. It originally flowed into Lake Michigan because it wasn't connected to the Illinois River.
