I’ve seen lots of stories but no dive reports :( I doubt the bottom less part because south Jersey was a sandbar and you would need rock to make a deep hole but I have been thinking about during the winter when the insect population is down and the ground is hard and not muck hiking in there, cutting a hole in the ice and dropping a lead line or getting a cheap fishfinder I can use on my boat later.
If you do want to mount a dive expedition I have a beach cart set-up to carry my tank and gear although hiking thru the pines in wetsuits would be a sight.
