Fontana Dam is a hydroelectric dam on the Little Tennessee River in Swain and Graham counties, North Carolina, United States.
 The dam is operated by the Tennessee Valley Authority, which built the dam in the early 1940s to accommodate the skyrocketing electricity demands in the Tennessee Valley at the height of World War II.
 At 480 ft high, Fontana is the tallest dam in the Eastern United States, and at the time of its construction, it was the fourth tallest dam in the world.
Fontana Dam (also known as Fontana Village) is a town in Graham County, North Carolina, United States.
 Fontana Dam is located on North Carolina Highway 28 near the Fontana Dam and the Little Tennessee River.
 The town incorporated in 2011 and has a full-time population of 33.
The Little Tennessee River is a 135 mi tributary of the Tennessee River that flows through the Blue Ridge Mountains of Georgia, North Carolina, and Tennessee, in the southeastern United States.
 It drains portions of three national forests— Chattahoochee, Nantahala, and Cherokee— and provides the southwestern boundary of the Great Smoky Mountains National Park.
 The river flows through five major impoundments: Fontana Dam, Cheoah Dam, Calderwood Dam, Chilhowee Dam, and Tellico Dam, and one smaller impoundment, Porters Bend Dam.
Watts Bar Dam is a hydroelectric dam on the Tennessee River in Meigs and Rhea counties in Tennessee, United States.
 The dam is one of nine dams on the main Tennessee River channel operated by the Tennessee Valley Authority, which built the dam in the early 1940s to provide flood control and electricity and to help create a continuous navigable channel along the entire length of the river.
 The dam is the technical boundary between the 39090 acre Watts Bar Lake— which it impounds— and Chickamauga Lake, which stretches from the dam's tailwaters southward to Chattanooga.
Fontana Lake is a reservoir impounded by Fontana Dam on the Little Tennessee River located in Graham and Swain counties in North Carolina.
 The lake forms part of the southern border of Great Smoky Mountains National Park and the northern border of part of the Nantahala National Forest.
 Depending on water levels, the lake is about 17 mi long.
 The eastern end is the Tuckasegee River near Bryson City.
 It has an average depth of 135 ft and reaches a maximum depth of 440 ft , making it the deepest lake in North Carolina.
 The lake has many inlets into coves and many islands formed from former mountain peaks, especially near the eastern end.
 As with most dam-impounded lakes, the steep banks are exposed when water levels are low.
 Many towns were submerged shortly after the creation of Fontana Lake, such as Proctor and Judson.
Chilhowee Dam is a hydroelectric dam located in Blount and Monroe counties, Tennessee, United States, between river mile 33 and 34 on the Little Tennessee River.
 Construction began in 1955 and was completed in 1957.
 The dam's reservoir covers approximately 1734 acre at normal full pool and has a drainage area of 1977 mi2 .
 The elevation of Chilhowee Reservoir is 874 ft above mean sea level (USGS).
 Chilhowee's powerhouse is equipped with three Kaplan turbines that have a combined generating capacity of 48 megawatts.
Calderwood Dam is a hydroelectric dam located along the Little Tennessee River in Blount and Monroe counties, in the U. S. state of Tennessee.
 Completed in 1930, the dam is owned and maintained by Tapoco, a subsidiary of the Aluminum Company of America (Alcoa), although the Tennessee Valley Authority controls the dam's reservoir levels from Fontana Dam further upstream.
 Calderwood Dam is named for Alcoa engineer Isaac Glidden Calderwood (1871–1941), who supervised much of the company's early Little Tennessee River operations.
The Cheoah Dam is a hydroelectric complex located in Graham and Swain counties, North Carolina on the Little Tennessee River between river miles 51 and 52.
 The Cheoah Development consists of a dam and powerhouse, the first of several constructed by the Tallassee Power Company, now Tapoco.
 The Cheoah project began in 1916 as a construction camp at the Narrows where the Little Tennessee River flowed through a narrow gorge, and was completed in 1919.
 Cheoah Dam helps form the long, narrow Cheoah Reservoir, which covers the approximately 644 acres of the normal full pool area and a drainage area of 1608 mi2 .
 The elevation of Cheoah Reservoir is 1276.8 ft (USGS).
 A scenic highway runs the length of the reservoir.
Santeetlah Dam is a hydroelectric development on the Cheoah River (river mile 9) in Graham County, North Carolina.
 The dam together with a pipeline/tunnel facility, and a powerhouse form the Santeetlah Development.
 The Santeetlah powerhouse is located on the left bank of the Cheoah Reservoir portion of the Little Tennessee River five miles (8 km) upstream of the Cheoah Dam.
MINIs on the Dragon is an annual gathering of MINI Coopers in Robbinsville, North Carolina.
 Started in 2003, the event takes place over the first weekend of May each year.
 The event is in part named after the legendary section of US 129 known as "The Dragon" which runs from North Carolina to Tennessee and has 318 curves in 11 miles.
 The event attracts over 900 attendees and over 600 MINI Coopers.
 The record was over 800 cars.
 The event primarily is attended by the newer BMW MINI Coopers but also attracts several classic Mini Coopers each year.
 This is the largest grassroots MINI Cooper event in the US each year.
 The event "headquarters" is in Fontana Village, a quaint vacation resort that was originally built to house the workers as they built the Fontana Dam during World War II.
 Each year MINI owners from over 30 different States and Canada make the pilgrimage to Fontana Village to participate in this event.
 Starting off as a three-day event, it has currently grown into its newer format of four days and includes a vendor alley, group dinners, a Brewswap, Bingo Night and a host of various drives and other activities, there is the Friday morning Dragon Parade, the Saturday night Midnight on the Dragon.
 Brave MINI's gather at Deals Gap and at 00:00 depart and drive the Dragon.
