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.
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.
A beached schooner barge. Compare the hull form with a square barge.
The schooner barge was the final development of the working sailing ship. The design originally evolved in the 1870s on the Great Lakes, where it was found that sailing ships could be more profitably towed from place to place than sailed. No longer subject to the vagaries of the wind, such trips could be made on a scheduled basis, and with reduced labor costs. The idea spread into general use, resulting in the conversion of many sailing ships into barges. Ironically, most of the vessels that were converted to schooner barges were not actually schooners, but square-rigged ships. Square-riggers, with their large and expensive crews of skilled sailors, became uneconomical to operate in the face of ever-improving steam power, while more efficient schooners managed to compete for a few years longer.
