Question: What structure does Proctor, North Carolina and Fontana Lake have in common?

full_context: Document 1: Hiwassee Dam: 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.
Document 2: Proctor, North Carolina: Proctor is a former town located in Swain County, North Carolina, U.S.A. It was on Hazel Creek. It is named after Moses Proctor, first white settler to this area. The town was flooded by Fontana Lake, which was created by the construction of the Fontana Dam, and remains submerged unless lake levels are very low.
Document 3: Badin Lake: Badin Lake is one of a series of lakes created by the damming of the Yadkin-Pee Dee River in the Uwharrie Lakes Region of the United States. The Badin Lake Dam was built in 1917 to support a local aluminum smelting plant (Alcoa), and the associated community of Badin was named for the founder, Adrien Badin. The power generation unit was sold to Cube Hydro Carolinas in February 2017. Badin Lake is in the Piedmont area of North Carolina. It is contained by Narrows Dam at the town of Badin, North Carolina. Sitting within a valley, the lake is very deep, with a maximum depth of 190 ft (58 m). The lake occupies 5350 acre and has 115 mi (185 km) of shoreline. Its waters have an average summer temperature of 84.4 °F (29.1 °C) and an average winter temperature of 50.6 °F (10.3 °C). No ferries cross Badin Lake. The northernmost point of Morrow Mountain State Park is roughly 2 mi downstream from Narrows Dam. The lake lies within Stanly, Davidson, Montgomery, and Rowan counties. Much of the lake's eastern shoreline lies within the Uwharrie National Forest.
Document 4: Swannanoa River: The Swannanoa River flows through the Swannanoa Valley of western North Carolina, and is a major tributary to the French Broad River. It begins at its headwaters in Black Mountain, NC, however, it also has a major tributary near its headwaters: Flat Creek, which begins on the slopes of Mount Mitchell. The Swannanoa River ends when it meets the French Broad at Biltmore Estate in Asheville. The river is 22 miles or 35 kilometers long, and it flows entirely within the geographical boundaries of Buncombe County. It is a valuable resource to the county, providing drinking water to the Asheville metropolitan area, and numerous recreational opportunities. In September 2004, massive rains from the remnants of Hurricane Frances and Hurricane Ivan caused the Swannanoa to flood, causing major damage to the Biltmore Village section of Asheville, and to the other communities that it flows through.
Document 5: Judson, Swain County, North Carolina: Judson was a small town in Swain County, North Carolina. It was submerged when the Fontana Dam was built, creating the Fontana Lake reservoir. Some structures can be visited when the lake is at its yearly low.
Document 6: Fontana Dam, North Carolina: 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.
Document 7: Mount Proctor: Mount Proctor is a mountain in British Columbia, Canada located near Fernie. Scaling 2393 m , this limestone mountain is home to a very popular hiking trail. The legend of Mount Proctor tells of a young Indian chief who could not decide whom to marry into the mountain. The Three Sisters peak facing Mount Proctor is said to be the three maidens. Before there was an Alpine resort at the Fernie Alpine Resort, there was an Alpine resort at Mount Proctor around 1960.
Document 8: Watauga Dam: Watauga Dam is a hydroelectric and flood control dam on the Watauga River in Carter County, in the U.S. state of Tennessee. It is owned and operated by the Tennessee Valley Authority, which built the dam in the 1940s as part of efforts to control flooding in the Tennessee River watershed. At 318 ft , Watauga is the second-highest dam in the TVA river and reservoir system (behind only Fontana), and at the time of its completion was one of the highest earth-and-rock dams in the United States. The dam impounds the TVA Watauga Reservoir of 6430 acre , and its tailwaters feed into Wilbur Lake. The Appalachian Trail crosses the top of Watauga Dam.
Document 9: Fontana Dam: 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.
Document 10: Lost Cove, North Carolina: Lost Cove is a ghost town in Yancey County, North Carolina. The town was first settled by Morgan Bailey shortly before the Civil War. The town is located in the Poplar Gorge above the Nolichucky River on the Tennessee-North Carolina border. Originally, the settlement was supported by logging, railroading, moonshine-making, and farming industries. Several factors contributed to the town's abandonment including rough terrain, isolation, and the end of passenger railroad stops. In 1957, the last family left Lost Cove, leaving it deserted. Fires in 2007 burned most of the structures down. Today, the town is still accessible to those willing to hike. Visitors to the area come to see the cemetery, Swin Miller's rusted Chevy still laying in a ditch, and the three houses that remain.
Document 11: Great Falls (Catawba River): The Great Falls of the Catawba River mark the point at which the river encounters a series of rapids while coursing across the Piedmont Plateau on the border of Lancaster County, South Carolina, and Chester County, South Carolina, near the town of Great Falls. Prior to the creation of the Fishing Creek Reservoir and other artificial lakes by Duke Power, the falls were a major landmark on the river. The rapids could be heard from long distances away, while a major pre-Columbian trading path ran near the left bank. Historically the Great Falls of the Catawba were approximately 4 miles long, with a total elevation drop of 121 feet. (The word "falls" was an 18th-century appellation, when any river rapids and vertical waterfalls alike were both referred to as falls.) The creation of the dams at Great Falls, South Carolina has resulted in the top 2 miles of it being completely dry (dewatered) except during times of very high flow. The bottom portion of historical Great Falls is drowned by Cedar Creek dam, another hydroelectric project. As of 2006, interest groups have formed in the Carolinas to restore the Great Falls by altering the dam and restoring flow to the dewatered stretch of Great Falls as part of a major restoration project of the Catawba River. As of 2007, a new licensing arrangement has been agreed to by Duke Energy and several interested parties.
Document 12: Hall Cabin: The Hall Cabin, also known as the J. H. Kress Cabin is a historic log cabin in Great Smoky Mountains National Park, about 15 mi from Fontana, North Carolina. The cabin is a rectangular split-log structure 24 ft wide and 17 ft deep, with a porch spanning its front. The gable ends of the roof are sheathed in board-and-batten siding. It was built by a man named Hall in 1910, and underwent some remodeling around 1940 when J. H. Kress used it as a hunting lodge. It is located in the drainage of Hazel Creek, an area which historically had a small population and was abandoned after the construction of Fontana Lake and the national park. It is the only structure remaining in its immediate vicinity.
Document 13: Kerr Lake: Kerr Lake /kɑr/ (officially John H. Kerr Reservoir, also known as Bugg's Island Lake) is a reservoir along the border of the U.S. states of North Carolina and Virginia. It is impounded by the John H. Kerr Dam, constructed between 1947 and 1952 to produce electricity and to provide flood control. Kerr Lake is owned by the US Army Corps of Engineers, and is the largest reservoir in Virginia. It is located in parts of Vance, Granville, and Warren counties in North Carolina, and Mecklenburg, Charlotte, and Halifax counties in Virginia. At its maximum capacity, it is one of the largest reservoirs in the Southeastern United States, covering approximately 50000 acre and bordered by over 850 mi of shoreline. The lake is named for Congressman John H. Kerr of North Carolina, who supported the original creation of the lake.
Document 14: Fontana Lake: 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.
Document 15: Lake Keowee: Lake Keowee is a man–made reservoir in the United States in the state of South Carolina. It was created to serve the needs of a power utility (Duke Energy) as well as public recreational purposes. It is approximately 26 mi long, 3 mi wide, with an average depth of 54 ft , and a shoreline measured at 300 mi in total, and is approximately 800 ft above sea level. It began in 1971 as a massive demolition and building project, including the construction of two large dams––Keowee Dam and Little River Dam––and covered 18372 acre of the state. The lake collects or "impounds" waters from the Keowee River and the Little River and others, and the outflows below the respective dams join to form the Seneca River which flows into the larger Savannah River. Lake water helps to cool Duke Energy's three nuclear reactors located at the Oconee Nuclear Generating Station. In addition, the force of falling water through gravity helps generate hydroelectric power. The Keowee Hydro Station generates 158 megawatts from the lake's outflows. In addition, Lake Keowee has been touted as a recreational destination for fishing, boating, swimming, sailing, kayaking and other watersports, and the lake has been described as having pure and clean water. The name "Keowee" (ᎨᎣᏫ) is a Cherokee name roughly translated as "place of the mullberries." The former Keowee River, which was inundated by Lake Keowee, had been part of the Cherokee Lower Towns region, and Keowee Town had been located on the bank of the Keowee River.
