Sea Girt Artificial Reef

3.6 Nautical Miles off Sea Girt, 1.33 sq miles
Depth: 60-75 ft [download]

The Sea Girt reef is located atop an underwater ridge known as the "Klondike". This is an area of clean sandy bottom and usually has relatively good visibility. Fish life abounds on all sites in this reef, although lobstering is slim. There are many more Army tanks than shown here, as well as quite a bit of concrete rubble scattered throughout the reef. The Sea Girt Reef is one of the oldest artificial reef sites in New Jersey. Reef-building activities at this site date back to 1937. Minimum clearance at mean low water is 50 feet.

If you look at the state's official record, linked above, the four older sites that are outside the official reef boundaries are not listed.

The 330-foot car float barge Liberty was removed from the Hudson River in sections to clear space for a new ferry terminal at Liberty State Park. Since 2005, Liberty was used at the park as a floating dock for ferries transiting to Ellis Island and the Statue of Liberty. It sank in a storm in 2020.
