Question: The Nolichucky River is a 115 mi river that flows through Western North Carolina and East Tennessee, the river is a tributary of which river that flows 218 mi from near the town of Rosman in Transylvania County, North Carolina, into the state of Tennessee?
Context: The French Broad River flows 218 mi from near the town of Rosman in Transylvania County, North Carolina, into the state of Tennessee.  Its confluence with the Holston River at Knoxville is the beginning of the Tennessee River.  The river flows through the counties of Transylvania, Buncombe, Henderson, and Madison in North Carolina, and Cocke, Jefferson, Sevier, and Knox in Tennessee, and drains large portions of the Pisgah National Forest and the Cherokee National Forest. The Nolichucky River is a 115 mi river that flows through Western North Carolina and East Tennessee, in the southeastern United States.  Traversing the Pisgah National Forest and the Cherokee National Forest in the Blue Ridge Mountains, the river's watershed is home to some of the highest mountains in the Appalachians, including Mount Mitchell, the highest point in the eastern United States.  The river is a tributary of the French Broad River, and is impounded by Nolichucky Dam near Greeneville, Tennessee. The Bald River is a river located in Monroe County, Tennessee in the Cherokee National Forest.  It is a tributary of the Tellico River.  Just before it empties into the Tellico, the river falls over a large waterfall, Bald River Falls, which is variously reported as being between 80 and 100 feet (25 and 30 m) high.  The river then flows under a bridge on Forest Service Road 120 (the falls and the river mouth are both very readily visible from the bridge).  The falls is regarded as the most impressive and scenic waterfall in East Tennessee.  The river is short in length but powerful as it flows through a steep, densely wooded valley and it is constantly replenished by the area's frequent rains.  It rises just north of the North Carolina state line near the crest of the Unicoi Mountains and flows northeast for a short distance before turning to the northwest. North Carolina Highway 215 (NC 215) is a highway in western North Carolina that runs from the town of Rosman in Transylvania County to Canton at Interstate 40 and U.S. Route 74 (US 74).  The portion from Canton to Rosman is a part of the National Forest Service's Forest Heritage Scenic Byway.  It travels high into the mountains along a scenic stretch of the upper West Fork of the Pigeon River, and intersects the Blue Ridge Parkway at Beech Gap at an elevation of approximately 5300 ft . The Chariton River is a 218 mi tributary to the Missouri River in southeast Iowa and northeast Missouri.  The river forms in southeastern Clarke County, Iowa.  It is dammed at 11000 acre Rathbun Reservoir in Appanoose County, Iowa and then flows 30 mi before entering Missouri where it forms the boundary between Putnam and Schuyler counties.  It enters the Missouri River in Chariton County near Keytesville.  112 mi are in Missouri and 106 mi are in Iowa.  The river has been called Missouri's "Grand Divide" because streams west of the Chariton flow into the Missouri and streams east of it flow into the Mississippi River. The Tallulah River is a 47.7 mi river in Georgia and North Carolina.  It begins in Clay County, North Carolina, near Standing Indian Mountain in the Southern Nantahala Wilderness and flows south into Georgia, crossing the state line into Towns County.  The river then travels through Rabun County and ends in Habersham County.  It cuts through the Tallulah Dome rock formation to form the Tallulah Gorge and its several waterfalls (collectively known as Tallulah Falls).  The Tallulah River intersects with the Chattooga River to form the Tugaloo River at Lake Tugalo in Habersham County, which then joins South Carolina's Seneca River at Lake Hartwell to create the Savannah River which flows southeastward into the Atlantic Ocean. The Bald Mountains are a mountain range rising along the border between Tennessee and North Carolina in the southeastern United States.  They are part of the Blue Ridge Mountain Province of the Southern Appalachian Mountains.  The Bald Mountains stretch from the Pigeon River in the south to the Nolichucky River in the north, and comprise parts of Cocke County, Greene County, and Unicoi County in Tennessee and parts of Madison County and Yancey County in North Carolina.  The Great Smoky Mountains border the range to the south, and the Unakas rise opposite the Nolichucky to the north.  The range gets its name from the relatively frequent occurrence of grassy balds atop the more prominent summits. The Whitewater River is a 14.6 mi river that flows south from headwaters in Transylvania County, North Carolina, over Upper Whitewater Falls and Lower Whitewater Falls before crossing into South Carolina and entering Lake Jocassee, the reservoir behind Lake Jocassee Dam. Opened in 1957, Tweetsie Railroad began as an excursion train ride pulled by steam locomotive #12, the only surviving narrow gauge engine of the East Tennessee and Western North Carolina Railroad (ET&WNC).  Built in 1917 by the Baldwin Locomotive Works, #12 is a narrow gauge 4-6-0 coal-fired locomotive that was used from 1918 to 1940 to haul passengers and freight over the ET&WNC's 66 mi line running through the Appalachian Mountains from Johnson City to Boone, North Carolina.  The name "Tweetsie" was given to the original East Tennessee and Western North Carolina Railroad by area residents who became accustomed to the shrill "tweet, tweet" of the train whistles that echoed through the mountains.  The nickname stuck with the railroad and its trains, and became more identifiable than the railroad's original name. The Pigeon River of western North Carolina and east Tennessee rises above Canton, North Carolina, is impounded by Walters Dam, enters Tennessee, and flows into the French Broad River, just past Newport, Tennessee.  The river traverses the Pisgah National Forest and the Cherokee National Forest, and drains much of the northeastern Great Smoky Mountains National Park.
