Carters Dam
- for the dam in Colorado, see Carter Lake Dam
Carters Dam is an earthen embankment dam located south of Chatsworth in Murray County and west of Ellijay in the U.S. state of Georgia. The dam is 445 feet (136 m) tall and is situated 26.8 miles (43.1 km) above the mouth of the Coosawattee River. The drainage area is 376 square miles (970 km2).[1]
It creates Carters Lake, the deepest lake in Georgia.[citation needed]
The dam took 15 years to build and was completed in 1977. The area of the primary flood control pool is 3,880 acres (1,570 ha). The top elevation of the dam is 1,112.3 feet (339.0 m). The top width of the dam is 40 feet (12 m).
The dam has a diversion tunnel that is 2,407 feet (734 m). It is a horseshoe shape with a bottom width of 2 feet (0.61 m) and a maximum height of 23 ft. The dam is constructed of rock and earth and is the tallest earthen dam east of Mississippi river. The lake is the deepest manmade reservoir east of Mississippi river. The created lake is more than 450 feet (140 m) deep and has 62 miles (100 km) of shoreline without any private docks or other development.[citation needed]
Hydroelectric plant
Below the dam is a 1,000-acre (400 ha) retention and re-regulation lake. The hydroelectric plant is of the pumped storage type. That is, during off-peak hours the water from the retention lake is pumped back up into the lake for use in generating power during the next time of peak demand. The dam's power station contains 2 X 125 megawatts (168,000 hp) Francis turbines and 2 X 125 MW Francis pump turbines for used in pumped-storage.[2]
