There is a water fall on the Ohio River?

Yes the river level falls 26 feet going by Louisville. A portage was required until a canal and locks were built in 1830. I heard that it cost one million and took five years to build. Of course this facility has been much improved over the years. The term used is The falls of the Ohio.

A couple miles from my hotel in Clarksville was the Falls of the Ohio Interpretation Center. What a grand thing just full of natural and historical displays. I really enjoyed my time there.

This is a statue of Lewis and Clark. Their historic journey to the Pacific Ocean started here.

I spent some time in the bird watching gallery.
