Sort of, there is an old train wreck in Delaware Water Gap on the Pa. side. The engines were pulled out but the boxcars filled with empty beer bottles remained. The boxcars have collapsed and despite park regs divers have taken many of the beer bottles :(
The farther down river you go the worse viz becomes :( I once tried to photo a commercial diver working on the pier at Fairless Steel Works near Bristol, viz was too bad for photos.
Near boat ramps you should find stuff lost off boats. Last year I was camping at Family Campgrounds in the gap, the river was running too high and fast for a dive :(
