Mission Dam is a dam on the Hiwassee River in Clay County, in the U.S. state of North Carolina. The dam is located between Hiwassee Dam and Chatuge Dam. The city of Andrews, North Carolina built the dam in 1924 at a cost of $500,000 to supply energy. [1] [2] The dam is the oldest on the river (other dams on along the Hiwassee were constructed in the 1940s). Nantahala Power and Light bought the facility in 1929 and upgraded it in 1943. [1] Unlike other dams on the river, it is operated by Duke Energy instead of the Tennessee Valley Authority. [3]
Mission Dam was built as an Ambursen type dam, but in 1999 many of its chambers were filled in due to concrete deterioration. [1] It is 50 feet (15 m) high and 397 feet (121 m) long.
The reservoir is 47 acres. [4] The dam is adjacent to a portage for canoe access downstream and a hiking trail on the path of the former Peavine Railroad which ran nearby.
Mission Dam is located 106 miles (170 km) above the mouth of the Hiwassee River, just upstream of the Cherokee County line.
The town of Hayesville, North Carolina and TVA's Chatuge Dam are located 9 miles and 15 miles upstream, respectively.
Clay County is a county located in the far western part of U.S. state North Carolina. As of the 2020 census, the county population was 11,089. The county seat is Hayesville.
The Tallulah River is a 47.7-mile-long (76.8 km) 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 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. The Tallulah River intersects with the Chattooga River to form the Tugaloo River at Lake Tugalo in Habersham County. It joins South Carolina's Seneca River at Lake Hartwell to form the Savannah River, which flows southeastward into the Atlantic Ocean.
The Hiwassee River originates from a spring on the north slope of Rocky Mountain in Towns County in the northern area of the State of Georgia. It flows northward into North Carolina before turning westward into Tennessee, flowing into the Tennessee River a few miles west of what is now State Route 58 in Meigs County, Tennessee. The river is about 147 miles (237 km) long.
Fort Loudoun Dam is a hydroelectric dam on the Tennessee River in Loudon County, Tennessee, in the southeastern United States. The dam is operated by the Tennessee Valley Authority (TVA), which built the dam in the early 1940s as part of a unified plan to provide electricity and flood control in the Tennessee Valley and create a continuous 652-mile (1,049 km) navigable river channel from Knoxville, Tennessee to Paducah, Kentucky. It is the uppermost of nine TVA dams on the Tennessee River.
The Nantahala River is a river in western North Carolina in the United States, within the Nantahala National Forest, and near the Great Smoky Mountains National Park. Two-lane U.S. Highway 19/74 runs along the river, picnic areas dotting the route. In 1839, this was an unimproved large path, part of what became known as the Trail of Tears as the Cherokee people were forcibly removed from their homelands in this region to west of the Mississippi River and Indian Territory.
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 satisfy the skyrocketing electricity demands in the Tennessee Valley to support the aluminum industry at the height of World War II; it also provided electricity to a formerly rural area.
The Nantahala National Forest is the largest of the four national forests in North Carolina, lying in the mountains and valleys of western North Carolina. The Nantahala is the second wettest region in the country, after the Pacific Northwest. Due to its environmental importance and historical ties with the Cherokee, the forest was officially established on January 29, 1920, by President Woodrow Wilson. The word "Nantahala" is a Cherokee derived, meaning "Land of the Noonday Sun." In some spots, the sun reaches the floors of the deep gorges of the forest only when it is high overhead at midday. This was part of the homeland of the historic Cherokee and their indigenous ancestors, who have occupied the region for thousands of years.
Sutton Lake is a 1,520-acre (6 km2) reservoir on the Elk River in Braxton and Webster counties, West Virginia. Sutton Lake is located just upstream of Sutton. It was authorized by Congress in the Flood Control Act of 1938. Construction of the dam began in 1956 and was completed in 1961. The dam is 210 feet (64 m) high, 1,178 feet (359 m) long, and constructed of concrete. The lake was named by Congressional action, Public Law 90-46, July 4, 1967.
Hiwassee is a small village in Cherokee County, North Carolina, United States, which sits next to the Hiwassee Dam and the artificially created Hiwassee Reservoir, on Hiwassee River. Hiwassee Dam had its own post office from 1937 until 1958.
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-mile (13.4 km) underground conduit carries water from the dam's reservoir to the powerhouse located 12 miles (19 km) downstream across the state line in Polk County, Tennessee. The dam and associated infrastructure were listed on the National Register of Historic Places in 2017.
Ocoee Dam No. 3 is a hydroelectric dam on the Ocoee River in Polk County, in the U.S. state of Tennessee. It is one of four dams on the Toccoa/Ocoee River owned and operated by the Tennessee Valley Authority, which built the dam in the early 1940s to meet emergency demands for electricity during World War II. The dam impounds the 360-acre (150 ha) Ocoee No. 3 Reservoir, which stretches 11 miles (18 km) upriver to the Tennessee-Georgia state line. Ocoee No. 3's powerhouse is actually located several miles downstream from the dam, and is fed by a 2.5-mile (4.0 km) conduit that carries water to it from the reservoir.
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 6,000 acres (2,400 ha), and its tailwaters are part of Apalachia Lake. At 307 feet (94 m), Hiwassee Dam is the highest overspill dam in the Eastern United States and third only to Shasta and Grand Coulee dams in the nation. At the time it was completed, it was the highest overspill dam in the world.
Nottely Dam is a hydroelectric and flood storage dam on the Nottely River in Union County, in the U.S. state of Georgia. The dam is owned and operated by the Tennessee Valley Authority, which built the dam in the early 1940s as a flood control structure and to help regulate flow at nearby Hiwassee Dam. The dam impounds the Lake Nottely of 4,180 acres (16.9 km2). While the dam was built primarily for flood storage, a generator was installed at Nottely in the 1950s, giving it a small hydroelectric output.
Chatuge Dam is a flood control and hydroelectric dam on the Hiwassee River in Clay County, in the U.S. state of North Carolina. The dam is the uppermost of three dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the early 1940s for flood storage and to provide flow regulation at Hiwassee Dam further downstream. The dam impounds the 7,000-acre (2,800 ha) Chatuge Lake, which straddles the North Carolina-Georgia state line. While originally built solely for flood storage, a generator installed at Chatuge in the 1950s gives the dam a small hydroelectric output. At the time it was built, Chatuge Dam was the highest earthen dam in the world until the Aswan Dam was built in Egypt in 1964. The dam and associated infrastructure was listed on the National Register of Historic Places in 2017.
North Carolina Highway 175 (NC 175) is a primary state highway in the U.S. state of North Carolina. The highway runs north from the Georgia state line to US 64, along the eastern banks of Chatuge Lake.
Nantahala Lake is located in Macon County, North Carolina in the western part of the state. The lake is regulated and maintained by Duke Energy and is a major source of hydroelectric power to the region. Nantahala is located at 3,000 feet (910 m) in the Nantahala National Forest.
Lake Chatuge is a man-made reservoir in Towns County, Georgia, and Clay County, North Carolina. It was formed by the Tennessee Valley Authority's construction of Chatuge Dam in 1942. The lake is relatively shallow with depths of 30 feet (9.1 m) and reaches 144 feet (44 m) by the dam. In an average year the water level varies 10 feet (3.0 m) from winter to summer to provide seasonal flood storage. Lake Chatuge is the highest major lake in the state of Georgia. It takes up 7,000 acres and is 13 miles (21 km) long.
Nantahala Township is located in North Carolina, United States in the part of Macon County which is west of Wayah Gap. It has a population of 1,711. "Nantahala" is a Cherokee word which means "The sun between them".
The H.F. Lee Energy Complex, formerly the Goldsboro Plant, is an electrical power generating complex operated by Duke Energy. The power complex was originally owned by the Carolina Power & Light Company, which inaugurated a coal-fired power plant in 1951. Two more coal plants were added in 1952 and 1962, and then oil-fueled turbines were added in 1967–71. In 2012 these units were shut down and replaced by four gas-fired units. The Quaker Neck Lake was built as a cooling pond for the coal-fired power stations, and is still used to supply cooling water. It was originally impounded by a low dam on the Neuse River, but in 1998 the dam was removed, while the lake remained contained in an earthen wall. This change allowed fish to migrate further upstream for spawning. Ash ponds near the lake hold toxic coal ash. There are plans to remove and recycle or bury the ash.
