Old thread, but I thought I'd update just the same. Just did this dive. Yes the directions on that web site led me astray, however my GPS fixed that up no problem. The twon is Wading River.
We were fortunate enough to have a small zodiac with us, so we put that in at the boat ramp and used that to get to the beach at the west jetty. I parked in the closest lot to the boat ramp - be careful if you do this - when we got back, the tide had come in and the lot was largely flooded. I was able to get out, but it was about 6 inches of water I had to drive through.
As I understand it, this is normally supposed to be a calm spot for diving. We must have caught it on an off day. There was a lot of chop going over, but managable. We shored the zodiac and went down the west jetty on the inside where the water was calm. Vis was about 5'. No bugs, but a lot of crabs. Once we got to the end of the jetty, vis suddenly dropped to 1-2' and the surge was very strong. I quickly lost my buddy and we both surfaced some small distance apart to find some good sized swells.
We elected to head back towards the plant more towards the center of the channel and see what was there and again quickly became separated. Once we regrouped, we elected to get back to the jetty and follow it back as visibility was rapidly approaching zero. This went as planned.
When we got back to the zodiac, we found it completely filled with water from the now very rough seas and started bailing it out. Long story short, we got back on some rough seas, but it stared to feel like a bad scene from Navy Seals. Still beats walking and traversing that river though.
Bottom line, I think this could be an amazing dive site and is definately worth checking out, we just caught it on a bad day. If you don't have the luxury of a small boat like we had, prepare for some lugging and beware that parking lot right next to the boat ramp.
