I looked on penn pilot, looks like the only thing thats changed is some trees are gone, and a new ponds been added, I think there is someone on the forum here from delano.
Correction, the new pond looks like some kind of reclamation pond area, the upper resevior is owned by service electric which owns alot of the upper wooded area, my father in law is very familiar with Delano, I will get with him for some more info.
