The topography on both sides of the creeks in this area is steeply sloping. Not a likely area for attempting bog operations.
Downstream towards New Lisbon and to the north bogs can be seen on the older maps that Bob posted and there are still active bogs on the road we drove in on.
The second map Bob posted shows what appears to be the canal we walked going directly into a bog near the railroad.
I think the primary purpose of the pond and canal system was more power related.
Look at Bob's second map and look at the elevation contours starting upstream of the area where we found the earthen dam. You are up in the 120 elevations and drop to around 70 a the dam. New Lisbon is down at 49.
There is an extraordinary amount of elevation difference along this stream corridor, especially for a coastal plain stream.
I think our industrious forefathers figured this out with some topographic surveying and were able to squeeze every HP out of this stream using the advantages of gravity.
Strangely, even today, gravity is free.

According to Volume III of the State Geologist Final Report (1894), the one on Water Supply, Upper Mill was out of service and Lower Mill, operated by Alfred L. Black at that time, had a fall of 7 feet, which generated 30 gross horsepower and 15 net horsepower.
