The Green River is a dam-release river that flows through the mountains of North Carolina, south of Asheville. The Green has numerous tributaries, but much of its water flows from a confluence with Big Hungry Creek. The Green River is itself a tributary of the Broad River. The river is dammed to form Lake Summit, in Tuxedo, North Carolina, and Lake Adger near Mill Spring, NC. The Green River is named for its deep green color but runs brown after heavy rains.

The Broad River is a principal tributary of the Congaree River, about 150 miles (240 km) long, in western North Carolina and northern South Carolina in the United States. Via the Congaree, it is part of the watershed of the Santee River, which flows to the Atlantic Ocean.
