Geography
Charles Mix County lies on the south line of South Dakota.

A smaller drainage flows south-southwesterly to the river along the east county line, separating it from Bon Homme County. The county terrain consists of rolling hills, mostly dedicated to agriculture. The terrain drops off into the river basin along the county's southwest side, but otherwise generally slopes to the southeast.
