Guppy isclosed as far as iknow, sub in potomac usually has1-2 ft of vis
I thought Guppy was still open, and in any case the OP wanted to break 100 ft. Guppy only goes to 80.
Willow Springs in PA is also shallow.
Mt Storm in WV could get you to 100 ft, but it is no longer open unless you dive from a boat. (No shore access)
Hyde's Quarry (MD) and Rappahanock/Fredricksburg (VA) are both too shallow.
