Via the west fork, considered to be the main stem of the river by the U.S. Board on Geographic Names, the White River is 362 miles (583 km) long. Indiana's capital, Indianapolis, is located along the river. The two forks meet just north of Petersburg and empty into the Wabash River at Mount Carmel, Illinois.
