Persponal Experience: At this point I have little to no information on the waterfall or dam. I have contacted the local historical society to see if they can help so hopefully this page will be updated! From what I can gather, the pond appears to have been part of a water treatment plant. Historic aerials show what looks like a water facility treatment southeast of the dam, built somewhere between 1953 and 1964 and removed or abandoned by 1989.
I have read stories online about people fishing in the pond decades ago but there is such an extreme overgrowth around the whole thing now that it's nearly impossible to fish there anymore. This seems to be an old, forgotten location that is still brimming with beauty and curiosity.
The dam reminds me of an abstract painitng!
