The Spoonville Dam, built on the Farmington River in 1899 below the Tariffville Gorge in East Granby, was breached in the Flood of 1955 and remained as a partial dam for several decades before being removed in July 2012. The dam, as well as the bridge crossing the Farmington River downstream at Route 187, derived its name from the silver plating factory erected in 1840 on the north bank of the river. It was the first factory of its kind in the United States.
