It is the fifth lake in a six-lake series created by hydroelectric dams operated by Georgia Power that follows the original course of the Tallulah River. The series starts upstream on the Tallulah River with Lake Burton followed by Lake Seed, Lake Rabun, Lake Tallulah Falls and Lake Tugalo, ending with Lake Yonah. The western arm of Lake Tugalo is filled by the Tallulah River and the eastern arm is filled by the Chattooga River. Georgia Power considers the lake full at a surface elevation of {{convert|891.5|ft|m}}.
Lake Tugalo began filling in 1923 with the completion of the Tugalo Dam, a gravity concrete and masonry dam. The dam is {{convert|155|ft|m}} high and has a span of {{convert|740|ft|m}}. The Tugalo Hydroelectric Plant has a generation capacity of 45 megawatts.
