Here is some previous pointers from another diver who has been there:

Best is to go around noon, the mountains do a remarkable job of blocking the light since it is like a canyon there. Also down river near the nj side is a great dive. There is all of the boulders from when they blasted rt 80. In the middle of the river from the wreck it drops off pretty quick to about 80ft. After about 40ft it is lights out so bring a good light. I like to put in at the welcome center on the jersey side and stage a car at the pa side. Put in in nj and do a drift dive to the wreck, and get out in pa."
