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.
