Lanier is the largest lake in Georgia, having nearly 700 miles of shoreline spread over 38,000 acres. The water in Lake Lanier comes from Georgia's Blue Ridge Mountains. The rain falls on the mountains, runs over beautiful waterfalls, and then makes its way down to Lake Lanier via the Chattahoochee and Chestatee Rivers. The completion of the Buford Dam on the south end of the lake in 1956 turned the area’s Chattahoochee and Chestatee Rivers into Lake Lanier.
