Sloat's Dam and Mill Pond

Originally created in 1792 by **Stephen Sloat** and later reinforced, [this dam](https://en.wikipedia.org/wiki/Sloat%27s_Dam_and_Mill_Pond) powered a sawmill, tannery, and later textile operations on the Ramapo River. The mill shut down after a mid-20th-century fire, but the dam remains mostly intact and is now part of a National Register historic property. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Sloat%27s_Dam_and_Mill_Pond)) - **Construction detail:** concrete skin over original stonework, with a surviving stone sluice gate and mill-race traces. - **Why it remains:** it is the only mostly intact survivor of the three historic dams that once supported milling here, and the county has worked to preserve the area for passive recreation.
