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 by the Tennessee Valley Authority (TVA) began in 1955 and was completed in 1957. The dam's reservoir (Chilhowee Lake) 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. Like Calderwood and Cheoah, Chilhowee is controlled by Fontana Dam. Fontana Dam is the primary flow control facility for the lower Little Tennessee River. Tapoco built and operates the Chilhowee Development. Chilhowee Dam and its powerhouse are listed on the National Register of Historic Places as the Chilhowee Hydroelectric Development. When the lake is drawn down for maintenance, the remains of the original bridge of US 129 over Abrams Creek can be seen.
