What 147 mile long river is dammed by the Apalachia Dam?
Hiwassee River The Hiwassee River has its headwaters on the north slope of Rocky Mountain in Towns County in northern Georgia and flows northward into North Carolina before turning westward into Tennessee, flowing into the Tennessee River a few miles west of State Route 58 in Meigs County, Tennessee. The river is 147 mi long.
Petit Jean River The Petit Jean River is a 113 mi river in west-central Arkansas. The river rises in the Ouachita Mountains in northern Scott County; it flows through Logan County and Yell County, defining the border between Yell County and Conway County before reaching its mouth at the Arkansas River north of Petit Jean State Park. The city of Danville, named after a steamboat that navigated the river in 1840, is the largest settlement on the river. Blue Mountain Lake, which straddles the border between Logan and Yell Counties, was created when the river was dammed in 1947. The river is the longest located entirely within the Arkansas River Valley.
