How far up the Tensaw river Alabama,( from Mobile) can one go in a 20ft motor boat?

Question

and can you trll me anything about boating on that river? thanks.

Answer 1

I had never thought of this question.  I googled the river, but there are so many branches and tributaries, it's hard to follow the river.  If you look at google maps, start at mobile bay and follow the river.  I found a route all the way to the tenn. line, but take a look for yourself.
