The NJDEP Division of Fish and Wildlife Artificial Reef Program is scheduled to begin deploying material on the new Delaware Bay Reef site beginning the second week of December 2017. The minimum vertical clearance is 15 feet below mean low water for all material placed on this site. A recent bathymetric survey was performed of the site and found depths ranging from 19 feet on the southwest corner to 35 feet midway between the northeast and southeast corners. This will result in material rising off the bottom from 4 feet to 20 feet respectively.

The reef site is approximately 1.13 square miles in area and is located approximately 9.2 nautical miles southwest of the Maurice River, bearing 188 degrees off Cumberland County, NJ.

NE  39 03.295' x 075 03.506'
SE  39 02.288' x 075 03.520'
SW  39 02.297' x 075 04.606'

The new reef will have a base of rock dynamited from a dredge site upriver near the Commodore Barry Bridge. Then concrete culverts and other material will be added on top. The rock varies from basketball size to the size of a car. The water is too shallow to use something larger, like a ship. The 1.3-square-mile area has a minimum depth of 19 feet deep and a maximum of 35 feet.

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.

Here are some ideas on minor yet important details that get little consideration. These topics are especially important to gear-laden New Jersey divers; much less so to unencumbered warm water divers.

A light and a knife are the first two non-essential accessories that you should get. Actually, neither one is non-essential, and only a fool would dive around here without both. Goody bags are used to carry booty from the sea. This includes food, treasure, and a lot of rusty junk that you're going to pick up because it is there. They can also be used to carry tools down with you.


2016 Update

Knives and bags haven't changed much in twenty years, but lights sure have. That section has been re-written to reflect modern technology. Nothing else new here, except that solid brass snaps have gotten harder to find and a lot more expensive. So if you find one on the bottom, leave it there for me!
