Question: What 147 mile long river is dammed by the Apalachia Dam?
Context: Farner is an unincorporated community in Polk County, Tennessee, United States.  Farner is located in a mountainous area along Tennessee State Route 68 near the North Carolina border, 9 mi north-northeast of Ducktown.  Farner has a post office with ZIP code 37333.  The Hiwassee River and Apalachia Dam are located just to the north. Hiwassee Dam is a hydroelectric dam on the Hiwassee River in Cherokee County, in the U.S. state of North Carolina.  It is one of three dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the late 1930s to bring flood control and electricity to the region.  The dam impounds the Hiwassee Lake of 6000 acre , and its tailwaters are part of Apalachia Lake.  At 307 ft , Hiwassee Dam is the third highest dam in the TVA system, behind only Fontana and Watauga. 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. The Afon Lwyd (English: Grey River ) is a 13-mile long river in south-east Wales which flows from its source north of Blaenavon, through Abersychan, Pontnewynydd, Pontypool, Llanfrechfa and Cwmbran before flowing into the River Usk at Caerleon, which subsequently flows into the Bristol Channel in Newport. Rossinver or Rosinver (Irish: "Ros Inbhir" , meaning "wooded estuary" ) is a small village in north County Leitrim, Ireland.  The village is at the southern shore of Lough Melvin.  The lake is home to two unusual species of trout - the "Gillaroo" and the "Sonaghan" - as well as the common brown trout.  There is a fishery at Eden Quay and boats and gillies are available locally.  There are some excellent walks in the area, in particular the mile long river walk to Fowley's Falls on the Glenaniff River which follows a series of waterfalls. The Lowe River is a 28 mile long river in Alaska.  It begins at glacier known as "Deserted Glacier" in the Chugach Mountains, passes through Keystone Canyon and flows into Prince William Sound near Valdez.  It was named by William R. Abercrombie in honor of Lt. Perceval Lowe, a member of an exploratory mission in the area led by Abercrombie. Apalachia Dam is a hydroelectric dam on the Hiwassee River in Cherokee County, in the U.S. state of North Carolina.  The dam is the lowermost of three dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the early 1940s to provide emergency power for aluminum production during World War II.  While the dam is in North Carolina, an 8.3 mi underground conduit carries water from the dam's reservoir to the powerhouse located 12 mi downstream across the state line in Polk County, Tennessee. The River Cerne is a ten mile long river in Dorset, England, which rises in the Chalk hills of the Dorset Downs at Minterne Magna, between High Stoy and Dogbury Hill, flows down a valley through Cerne Abbas and Charminster, and flows into the River Frome in Dorchester.  The Cerne Valley lies in the Dorset Area of Outstanding Natural Beauty. The Mutha River is a river in western Maharashtra, India.  It arises in the Western Ghats and flows eastward until it merges with the Mula River in the city of Pune.  It has been dammed twice, first at the Panshet Dam (on the Ambi River), used as a source of drinking water for Pune city and irrigation.  The water released here is dammed again at Khadakwasla and is an important source of drinking water for Pune.  One more dam has been built later on the Mutha river at Temghar. The Water of Ken is a river in Galloway, south-west Scotland.  It rises on Blacklorg Hill, north-east of Cairnsmore of Carsphairn in the Carsphairn hills, and flows south-westward into the Glenkens valley, passing through Carsfad and Earlstoun lochs, both of which are dammed to supply the Galloway Hydro Electric Scheme.  From there, the river flows south, passing St. John's Town of Dalry and New Galloway, before widening to form the 11-mile long Loch Ken.  The River Dee also enters halfway down the loch, and from Glenlochar, at the south end of the loch, the river continues as the Dee towards Kirkcudbright and the coast.
