This bay is muddy and turbid, although some folks dive the several small wrecks around the inside of Sandy Hook. Bottle hunting around the old piers and pilings in Keyport harbor is also a possibility, but most of the structures along the bay shore are too small and shallow to be of interest. I have scouted the shoreline from Atlantic Highlands to Laurence Harbor, and nothing looks too promising. See also entries on Navesink River and Horseshoe Cove.
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.
