Since the water flow of the Hocking River is rather low, you can see the sandstone cap from which he cut the stones for his foundation.. He built a 10-foot high wooden crib dam. The person I talked to in the store said they made the dam with 10-foot rectangles of big wood beams and filled the wood crib with debris. In 1895 the wooden water waterwheel was replaced by a turbine. The dam was lined with concrete in 1900. The mill has had a few dam rebuilds because of floods, one fire that burned it down to the sandstone foundation, and a few owners. [scificincinnati]
The following video has several scenes of the milling equipment that was inside the building.
Athens County Habitat for Humanity. Their office on the right was closed, but the entrance is open dawn to dusk so that users of the Hockhocking Adena Bikeway can use the restrooms.
the former B&O+NYC+HV depot was closer to downtown. So the ancestry of this building remains a mystery.
From the previous days photos, we know that there is a "trough" in the middle of the river where the water normally flows. When the river is high, this trough allows more cubic-feet-per-second to pass in the middle. I took this wide angle to try to capture that you could actually see the water "hump" up in the middle of the downstream part to accommodate all of the water that was flowing through the trough. This is another form of a hydraulic jump --- water above the normal water level to accommodate a faster flow of water into a slower pool of water.
Then I took another video from downstream to try to capture the "hump" of water in the middle of the river do to the hydraulic jump caused by the larger volume of water flowing through the "trough" next to the sandstone cap. You can see that the hump is higher in the middle than at the bank quite a ways downstream and that some of the water flowing to the bank of the river then flows upstream to create a whirlpool.
I see both the satellite sites I use caught the river when the flow was even lower than the first day I visited.
