Re: Raystown Lake, PA
Sorry I didn't see this earlier ...
Raystown becomes a zoo around noon on Friday through 5 pm on Sunday. Wednesdays are a little crowded, but the rest of the time it is pretty wide open.
As for diving spots - there are a few interesting places, depending on your abilities (the deepest spots in the lake are over 180 feet deep). Between mile marker 2 and 3 on the old channel is the old dam. It has been blown up, but the rubble is there ... but you need to be able to dive to about 150 feet.
Across from Mile marker 6, there is a road that comes into the water. Follow that road and you will swim by an old stone house. It was not destroyed when the built the new dam.
Also in that area are "The Cliffs." Sheer rock ledge holds some interesting rock formations and aquatic life.
There are 2 bridges (Finks and Entricken) that were blown up also, with the rubble still at the bottom.
Many other natural places of interest as well.
I am not a certified diver, so my experience diving has been limited, but I used to live on the old lake, so I watched these places being flooded ...
