The Whitewater River is a significant waterway spanning approximately 101 miles through southeastern Indiana and southwestern Ohio. Despite its name suggesting turbulent waters, the river generally features a gentle flow throughout most of its course, though it does contain multiple rapids due to its steep gradient (falling an average of six feet per mile, making it one of the swiftest rivers in Indiana). The river is formed by the confluence of the East Fork and West Fork. The West Fork runs 69.5 miles from Randolph County, Indiana, flowing southerly and southeasterly past Connersville and Hagerstown. The East Fork flows 56.7 miles from Darke County in Ohio, going south past Richmond until it meets the West Fork in the town of Brookville. After the forks merge, the Whitewater River continues southeasterly into Ohio where it eventually joins the Great Miami River, a tributary of the Ohio River.
