The Tainter gate is a type of radial arm floodgate used in dams and canal locks to control water flow. It is named for its inventor, the Wisconsin structural engineer Jeremiah Burnham Tainter.[1]

Tainter, an employee of the lumber firm Knapp, Stout and Co., invented the gate in 1886 for use on the company's dam that forms Lake Menomin in the United States.[1]
