Course

The Ocheyedan River flows from Ocheda Lake in Nobles County, Minnesota, 3 mi (4.8 km) south of Worthington, and flows generally southeastwardly through Osceola, O'Brien and Clay Counties in Iowa. It joins the Little Sioux River at the town of Spencer.[5][6]

In Osceola County, the river collects the short Little Ocheyedan River, which rises near Hawkeye Point (the highest elevation in Iowa) and flows southeastwardly.[7]
