These photos show the remains of the dam.










These photos focus on the sluice that controlled the flow of water through the underwater turbine that powered the mill.




There were two dams: the original one (wooden), and a new one built circa 1920 (concrete). We don't know if the new one replaced the old in exactly the same location. Dan intends to look for any remains of the old wooden dam when time permits.
From another local historian, we have these two photographs of the concrete dam dating to the 1920s.

The second one appears to have been taken from the Lincoln Highway (73rd Avenue) bridge over the Deep River.
