Shiawassee County

Shiawassee County is an administrative division in Michigan encompassing several communities. The Shiawassee River connects these settlements including Byron, Vernon, Corunna, and Owosso as it flows toward Saginaw Bay.

The Michigan Territorial Legislature established the county in 1822 by taking portions from Oakland and St. Clair counties. Official organization occurred in 1837, solidifying its status as a distinct administrative region.

The county name comes from a Native American language meaning flowing or glimmering water. Communities throughout the area maintain this connection to water in their daily routines and local identity.

County services are available at the Surbeck Building in Corunna, where administrative offices operate during business hours. Visitors should plan ahead and verify what services they need before traveling to the main office location.

Owosso, the largest city in the county, was home to Thomas Dewey who later became Governor of New York. Author James Oliver Curwood also hailed from this area and left a mark on its literary history.
