Last weekend, we took an unexpected field trip to another New Hampshire dam built by the Army Corps of Engineers, the Hopkinton Dam, one of two dams that form Hopkinton-Everett Lake. (Yes, the other one is called Everett Dam). They were built in 1962 for $21.4 million. And it’s not so much a lake as two reservoirs connected by a canal when there’s a flood.
Hopkinton Dam is on the Contoocook River; Everett is on the Piscataquog River. Along with 3 other dams in the Merrimack River Basin, they control flood waters to the south, in Concord and Nashua NH and in Lowell, Lawrence and Haverhill, MA. Hopkinton and Everett Reservoirs can together hold 50 billion gallons of water.
We stumbled on the Hopkinton Dam, and the unrelated Rowell Covered Bridge nearby (see next posting), when we were looking at kennels in Warner and Henniker; the Hopkinton Dam is just over the Henniker town line. Fortunately, I had my camera!
