Eel River (White River)
The Eel River is a 52.8-mile-long (85.0 km) tributary of the White River in southwestern Indiana. Via the White, Wabash, and Ohio rivers, its waters flow to the Mississippi River and the Gulf of Mexico. The Eel River flows through Greene, Owen, Clay, and Putnam counties.
The river forms in southwestern Putnam County at the confluence of Mill Creek and Big Walnut Creek. It runs generally south and slightly west for most of its course until it takes a southeast turn about 4 miles (6.4 km) west of Middlebury. It then flows about 18 miles (29 km) to its junction with the White River near Worthington. One of its tributaries, Big Walnut Creek, has a drainage basin of 318 square miles (820 km2). Another tributary is Mill Creek, which flows into Cagles Mill Lake, also known as Cataract Lake, before joining the Eel.
