area is Toledo, far west end of erie, this end of the lake i shallow, the bay here averages about 6 feet, gt a little further out is avgs 12-15 then averages 25 ' or so on this half of the lake. a strong sw wind can drop this end of the lake 6' in a day. it's hell on props around here too.. if it blows good for a couple days the water can actually go out a couple miles. happens in the early spring and the fall. Checked the bertram (all th way out at the deepest part of the marina) after work and the sten lines were tight, busted one loose and the boat dropped over 6 inches.
