Ben:
I can’t speak with certainty here—and I can’t explain why the center channel does not appear on the historic maps—but with the forge working off the one raceway and the sawmill operating on the main stream, if you have the gates shut on both head races, then you still need a way to allow the water to spill over the dam. Hence, the center channel may have served as a bypass race for the two mills. The 1858 map has a tantalizing little point in the middle of the dam area right from where that center channel would extend.
I will see what else I can find.
Best regards,
Jerseyman
