Early photo of Dart's Stone Mill
The trees along the edge of the river have been cleared out recently
This turbine house was added sometime around 1903. The penstock feeding the turbine comes out through the basement of the main building then curves into the smaller annex that houses the turbine. You can baerly make out the draft tube behind the wooden weather wall. The bottom was hinged to let the tailwater flow out, but kept ice and trash from backing up around the tube.
Possible the tailwater discharge of Dart's famous 40ft . There is an arch opening (bricked up now) higher up the adjacent wall and next to the arched tunnel where the river flows under the building. I'm making an educated guess that it was the over flow or spillway for the large wheel.
This is a hand colored postcard from the late 1800's. The painter look some liberty to add a race for the water coming out of the tunnel. There was never a tail race here.
Early photo showing the dam that was inbetween the two buildings. Once the turbine house was added, the water flow was changed and the dam covered over with fill.
Brand new powerhouse. Notice the building addition to the left, built on piling out over the water. That was the restroom. Glad they don't do that anymore.
