Bad

St. Charles was a significant transport point for floating lumber, as the north and south branches of the Bad River, as well as Swan Creek, met at this point.

The lands of the township are drained by the Shiawassee River, which passes from south to north through its center, while the Bad River and its branches course through its northwestern corner. The soil of the township is fertile, and consists of various kinds, such as sandy clay, loam, gravel, etc. Originally its lands were covered by a dense growth of forest of various kinds of hard-wood and pine.
