History
Ingham County was established by an act of the Michigan Territorial Legislature on October 29, 1829, from portions of Shiawassee County, Washtenaw County and unorganized territory. It was attached for administrative purposes to Washtenaw County until 1838 when county government was established for Ingham.
The county consists of gently rolling hills with an elevation ranging between 800 and 1,000 feet above sea level. The highest point in the county is the top of Teaspoon Hill rising to a height of 1,056 feet above sea level 1.5 miles north of Leslie.
The Grand River winds northward along the western boundary of the county and the Red Cedar River flows west across the northern section into the Grand River in Lansing. Most of the midsection of the county drains to the north into the Red Cedar River and the northern tier of townships drain to the south into the Cedar. The Sycamore Creek, flowing northwest into the Red Cedar in Lansing, drains much of the midsection of the county. Most of the southern portion of the county drains south or west into the Grand River. The southeastern corner drains to the southeast into the Huron River via the Portage Creek and Portage River and a series of small lakes.
