I have my dock ramp connected to the top of a four foot sea wall that is topped with a sidewalk. I don’t think it will get that high but it will be close. I have my dock power on a good ground fault breaker that is on a local disconnect on the other side of the sidewalk three foot above that grade. Should go off automatically and instantly at the slightest ground fault — or it did the last time I had it tested.
My only concern is the dock cables will be at a real odd angle with the lake that high and I hope that the ramp doesn’t collapse from the tension or tear out the cables which has happened from ice lock up when my aerator went out.
I think main arm boating to see the fireworks displays is going to have a lot of boaters hitting flood debris in the night-time run home.
Maybe they're getting a handle on this...
