Freshwater Dive Sites

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.



Dutch Springs contains many interesting artificial reefs for divers to explore. In fact, even the hole itself is man-made - it is an old limestone quarry.

Although all of the land-side facilities have been demolished to make room for warehouses, the quarry itself is still open in a limited way - training dives only.


Round Valley Reservoir
Looking roughly southeast, with the diving cove in the foreground. The natural basin of the valley is evident, as well as one of the two dams, at right. The water level looks pretty high, with a little snow on the ground.
Type:
freshwater artificial reservoir
Depth:
180 ft, but less than 60 ft in the usual area

Comb Jelly

You cannot go diving in New Jersey waters without seeing Comb Jellies. Up close, rainbow-like rows of tiny beating hairs called cilia may be seen - the Comb Jelly's only means of propulsion. Comb jellies do not sting, but they are still voracious predators, feeding on anything they can engulf. At night they may phosphoresce - watch the boat wake as agitated Comb Jellies flash in the dark like depth charges. Cnidarians are exclusively marine, although some are tolerant of brackish water as well.
