Freshwater
There aren't too many options for freshwater diving around here. That's not to say that you can't try jumping into any body of water you find, but most of them are likely to be pretty awful, and a few could get you arrested. Two good freshwater dives in the region are Round Valley Reservoir and the Delaware River Water Gap. Some diving is also done in Lake Hopatcong, although access is a problem.

Although all of the land-side facilities have been demolished to make room for warehouses, the quarry itself is still open in a limited way - training dives only.
