Ticonderoga in Essex County, New York — The American Northeast (Mid-Atlantic)
This dam gets its name from its position as the third dam down from the outlet of Lake George. It was the last location to be exploited along the LaChute. This site required a broad dam high enough to make its power-generating "head” worthwhile, and strong enough to hold back a lot of water.
Earthen berms on either side of the stream indicate the height of the original dam and give an idea of the extent of the pond it created. When International Paper Company built a new mill on the shore of Lake Champlain in 1971, the turbine house was dismantled and the dam was lowered to decrease the depth of the pond.
The energy crisis of the 1970s prompted a new interest in small-scale hydropower. The extraordinary waterpower resources here attracted the attention of Consolidated Hydro, which re-engineered the River corridor to produce electricity. An underground penstock delivers water to the upper generating station located in the small building next to the dam.
