The Clarksville ramp is nice, but if they change the water release you can be in big trouble trying to recover your boat on the trailer. Been there,done that.

That's why I currently use the New Albany ramp under I-64. Yeh, the ramp and access are in bad shape but I feel safer there with truck and trailer parked as the area is patrolled regularly.

There are a few submerged rocks on that ramp, so be careful, stay to the shore side of the ramp. River side of the ramp has a nasty dropoff that can grab trailers.
