Factory Dam Operating Mechanisms in Pittsfield, New Hampshire

Today we take a look at the Factory Dam Operating Mechanisms in Pittsfield, New Hampshire:

“This dam was built in 1920 replacing a wooden one constructed in 1883.  Its purpose was to supply power tot he Cotton Mill downstream owned by Exeter Manufacturing Company.  It is 422 feet long, 21 feet high and has an ogee spillway of 139 feet.  These two gate operating mechanisms were located above the east abutment of the dam.  Manufactured in Keen by L.B. Dow, Inc., they had to be operated manually by rotating the two large wheels in the front.  It took approximately four hours for two men to raise or lower the gates in high water.  During the “Mother’s Day Flood” of 2006, the gears were stripped and because of this and other problems with their operation, they were replaced by the State of New Hampshire with more modern apparatus that can be operated manually.”
