The Little Tennessee River flows along Monroe County's border with Blount County to the northeast. Three artificial lakes— Tellico Lake, Chilhowee Lake and Calderwood Lake— were developed in this section of the river. The Tellico River, a tributary of the Little Tennessee, drains much of the southwestern part of the county. The Bald River, noted for scenic Bald River Falls, is a tributary of the Tellico River. Sweetwater Creek, a tributary of the Tennessee River, drains a portion of northern Monroe County.
