This is the back up/ alternate reservoir for Williamstown. Actually located just across the border in Pownal, about 7 min from campus by car, it is fenced in, and not legal to swim there.
It was a common location back before the fence in the 80s, and visitors were met with cold, cold water… and naked chases if the watershed managers/workers caught you skinny dipping.
Location is left out due to trespassing considerations. You need to befriend a local to find this one.
