The western Sound has what could be the highest concentration of wrecks in the US. This is because of the ship dumping grounds between Stampford, CT and Eatons Neck, NY.
Depths can run from zero to 190' just north of Eatons Neck. In the 2001 to 2006 surveys of the shipping channel and approaches to the major Harbors NOAA found over 130 unknown wrecks. In one survey run they found 5 wrecks and might have found more but they put the sonar towfish into the 5th.
But, vis will run from 15 to 20 in late February to zero in August and there are places that you can only dive at slack tide.
Put together the low vis, current, depth, and entanglements from mono and lobsterpot lines can make the dives very chalenging.
Right now we are diving:
Lightship LV-51 depth 190'
A110' Sub Chaser/Rum Runner at 110'
The Steamboat Washington in 60'
What may be the Steamboat Lexington in 145 (real challenge due to vis and entanglements)
A small intact tug in 150 near the Lex
A costal freighter in 110 near Middleground
