Most of the Caddo historically lived in the Piney Woods ecoregion of the United States, divided among the state regions of East Texas, southern Arkansas, western Louisiana, and southeastern Oklahoma. This region extends up to the foothills of the Ozarks.
It then opens up into a wider expanse of water, called âBig Lakeâ. In 1914, an earthen spillway was erected, which marks the eastern edge of Caddo Lake in Mooringsport, Louisiana. Caddo Lake empties into Twelve Mile Bayou, the Atchafalaya River, the Mississippi River, and the Gulf of Mexico.
