Via the Big Sioux and Missouri rivers, it is part of the watershed of the Mississippi River. CourseThe Rock River starts in Pipestone County, Minnesota, approximately {{convert|13|mi}} northeast of the town of Pipestone, and flows initially southwardly through Rock County, Minnesota, and Lyon County, Iowa, where it turns southwestward into Sioux County, Iowa. It flows into the Big Sioux River in Sioux County, {{convert|6|mi|0}} north of Hawarden. Along its course the Rock River passes the towns of Holland, Edgerton, Luverne and Ash Creek in Minnesota; and the towns of Rock Rapids, Doon and Rock Valley in Iowa. TributariesIn its upper course in Minnesota, the river collects the East Branch Rock River, about {{convert|15|mi}} long, which flows for its entire length in Pipestone County. In Iowa, it collects the Little Rock River just south of Doon. See also
