The source for South Blount's water is Lake Tellico. Lake Tellico was created in the late 1970's by TVA (Tennessee Valley Authority) when the construction of the Tellico Dam was completed. Lake Tellico is most known for recreation and includes many areas that offer boat ramps, day-use areas, campgrounds, and fishing (specifically trout and bass fishing).
Here are some facts about Lake Tellico and the Tellico Dam:
• Tellico Dam is located on Little Tennessee River arm of Watts Bar Reservoir, .3 miles above the confluence with the Tennessee River in Loudon County, Tennessee.
• Construction of Tellico Dam began in 1967 and was completed in 1979.
• The dam is 129 feet high and stretches 3,238 feet across the Little Tennessee River.
• The reservoir has a flood storage capacity of 120,000 acre-feet.
• Tellico Dam is not a hydroelectric facility. It has no power generators and produces no electricity. However, water from Tellico flows through a short canal into Fort Loudoun Reservoir and helps drive the four generating units at Fort Loudoun Dam.
• On Tellico’s banks is a reconstruction of the original Fort Loudoun, which was built by the British during the French and Indian War. It was named for John Campbell, the fourth Earl of Loudoun, commander-in-chief of the British forces in North America, at the time. Another nearby historic attraction is the Sequoyah Birthplace Museum, honoring the genius who invented the Cherokee alphabet.
