That is as close to a tide as we get. The wind kind of sloshes the water to one side or the other of this big bathtub called Lake Erie. Water movement can be a couple of feet in an hour or so. To answer your questions though, the water has been as high as the sidewalk which is on the other side of our boat. That was when the lake level was high and the wind was from the west for a few days. Right now we are about 3 feet below that.
