One of the few natural lakes in Texas, Caddo Lake looks like something out of a slightly dark fairy tale. Long tendrils of Spanish moss hang from cypress trees, and the surface of the lake often appears black due to the dappled sunlight and decaying leaves in the water. he lake is named after the Southeastern culture of Native Americans called Caddoans or Caddo, who lived in the area until their expulsion in the 19th century. It is an internationally protected wetland under the Ramsar Convention and includes one of the largest flooded cypress forests in the United States. Caddo is one of Texas’s few non-oxbow natural lakes and is the 2nd largest in the South; however, it was artificially altered by the addition of a dam in the 1900s.
