Lake Zumbro Hydroelectric Generating Plant

The Lake Zumbro Hydroelectric Generating Plant, also known as the City of Rochester Municipal Hydro-Electric Plant, is a hydroelectric facility on the Zumbro River in Mazeppa and Zumbro Townships in the U. S. State of Minnesota. The facility consists of a gravity dam and a powerhouse, and formerly included three houses for the plant operators. The houses were removed in the 1960s when the dam was retrofitted to allow remote operation of the generating equipment from Rochester. The impoundment created is called Lake Zumbro. This dam spans 904 feet (276 m) and is 66 feet (20 m) high, creating a reservoir with about 55 feet (17 m) of hydraulic head.
