You can access that area with a boat from the Ohio. It's a lot easier in an aluminum boat through, there are some spots that shallow out a little bit when it's down in the summer, but I've never had to get out and pull the boat. It's a 17 footer so not tiny.
I usually use the boat ramp on Locust Pike when I fish that area (It's an awful ramp and needs repair). It gets the job done though.
