All manner of concrete, steel, and stone rubble from dredging, demolition projects, and other construction is used as artificial reef materials. This material is generally available at very low cost or free from construction companies who are more than happy to get rid of it. Transportation costs determine where this material is used by the Reef Program.

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.
