The City of Menomonie has a mayor/city council form of government with eleven council persons elected on a ward basis.Each of Dunn County‘s 29 cities, villages and townships is governed by an elected council and mayor, village or town boards.
Dunn County was formed out of a portion of Chippewa County on February 19, 1854. The “Seat of Justice” for the county was originally located in Dunnville, near the mouth of the Red Cedar River. When it burned to the ground in 1858, the county seat was moved to Menomonie, where it has remained.
The name for the county was derived from Charles Dunn, the first Chief Justice of the Supreme Court of the Wisconsin Territory, appointed by Andrew Jackson in 1835. The county covers 858 square miles.
