These two water turbines were probably the largest and nearly the most powerful ever built in the United States, supplying direct mechanical power to a manufacturing plant. Their installation between 1871 and 1873 makes them among the oldest surviving water turbines. A dam at Cohoes diverted water to mills and factories along a power canal system. The vertical-shaft turbines at the mill were said to run at 800 horsepower (600 kilowatt) under a head of 20 feet and were connected to an overhead shaft by bevel gearing.
