I remember long ago that Lake Erie was really low. At that time, I was at a fixed dock so my boat was well below the finger. I always have said I needed a parachute to get into my boat. But the other concern was the launch ramp. Normally its deep enough you can't see the end of it. But with the lower level, it was becoming visible and it began to worry me because the ramp didn't just smoothly come to an end. It stopped abruptly with maybe 1 foot higher than the bottom. Eventually, you would not be able to launch or retrieve. I kept a close eye on that ramp and water levels that year. I'm not sure what the ramps are like underwater at the marina I'm at now. To deep to see. Works for meeeee.
