History
Saginaw Township predates its parent county. When Saginaw Township was organized as part of Oakland County in 1831, in accordance with an 1830 act of Michigan's Territorial Legislature, it covered all of today's Saginaw County and part of Bay, Genesee and Midland counties. As the boundaries for these counties were set, and new townships within Saginaw County organized, Saginaw Township was reduced to its present boundaries. The territory of the present City of Saginaw west of the Saginaw River was taken from Saginaw Township when the city of Saginaw was incorporated in 1857. In May 2020, Sagninaw Township residents. along with other Midland County residents in parts of the city of Midland, the village of Sanford, Edenville Township, Midland Township, Tittabawassee, Thomas Township, Lincoln Township, Homer Township and Dow Chemical, were forced to evacuate due to high flooding which was caused by the breach of the Edenville and Sanford dams.
