Exploring Steam Paddler wrecks in the Missisippi river?

I was reading a book when I was a kid about steam paddlers on the Mississippi, and a race between two boats from New Orleans to Baton Rouge. The story happened sometime between 1850 and 1900 as far as I remember and stated that quite a few ships ran aground or got stuck in the Mississippi during this time because the river changed its way across the landscape quite often, particularly after heavy rain upstream or flooding.

So my question is: Did they have steam ship races during this time on the Mississippi, and are there any beached steam ship wrecks left somewhere on the river that can be explored?
