The two ramps that some use down from the dam are helms and winfreys, but they shallow up pretty quick with no generation and winfrey's is a booger to back into...it has a 90 degree left hand turn. I assume you'll be using an alum. boat...I wouldn't use fiberglass.

You can go on the dept. of wildlife and get some directions to the ramps.

Burksville is probably your best bet if you want to travel that far.
