Delaware Artificial Reefs

Delaware Artificial Reefs (and a few New Jersey reefs)

Coverage of Delaware is restricted to just those sites that are in the ocean and vessels in the bay. Siting reefs has been tricky for Delaware, as they must be kept clear of the shipping lanes. This doesn't leave a lot of places that are both located in usefully deep water and a convenient distance from shore. Cape May Reef belongs to New Jersey, but is within range of Delaware, and lately seems to have received material from Delaware. I have also included the USS Blenny, to the south - drag the chart.

Delaware has eight permitted reefs in the Delaware Bay, and another way offshore that is undeveloped and will likely stay that way.

Site #8 has a 70' tugboat "Golden Eagle". Site #6 has a 120' barge. Site #1 has a 40' pilot boat. Other than that, the Delaware Bay reefs are all concrete rubble.

Delaware Artificial Reefs

Delaware has a string of artificial reef sites in the Delaware bay, but they are of little interest to divers. Most of the sites are quite shallow and perilously close to the shipping lanes, several of them were actually reduced for this reason. The conditions in the bay are hardly good for diving. The reefs consist mostly of concrete rubble from construction in Philadelphia and other cities on the river. Also shown is New Jersey's sole artificial reef in the bay.

The Artificial Reef Program used four types of obsolete Army armored vehicles as artificial reef materials off the New Jersey coast. These were cleaned at local military bases, loaded onto barges for transport, and pushed off at their final destination. Once the Army had disposed of its excess inventory, the program ceased, around 1999. The Artificial Reef Program has sunk almost 400 tanks altogether, far too many to list them here in this website.



Spider Crab

Spider Crabs Libinia emarginata are scavengers. Although they are fearsome-looking, they are actually slow-moving, and their usual claws-out threat display is mostly bluff. Spider Crabs have relatively small round bodies (to 4"), long legs, and rather weak claws. They are found subtidally to at least 160 ft, on any type of bottom, and are very common in rivers and inlets. They often cover themselves with detritus for camouflage, and can also burrow in soft sediments.
