Oronoco Township of Olmsted County, Minnesota

Oronoco Township is on the northern border of Olmsted County, Minnesota. The population was 2,200 at the 2010 census and was named for the city of Oronoco. The city was named by early settler Dr. Hector Galloway who moved to Minnesota from Michigan. He named the city after the similarly spelled Orinoco, a large river in South America. A village was founded in 1854 and platted in 1855. It incorporated as a city on March 6, 1968. Oronoco Township, which surrounds the city on the North, East and South sides, was organized in 1858. It is a bedroom community for nearby Rochester.
