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.
Caddo Lake State Park sits west of the lake, along Cypress Bayou. Caddo Lake is a maze of slow-moving bayous, wetlands and backwaters. It covers about 26,810 acres of cypress swamp, depending on rainfall. Although a natural logjam created Caddo Lake, today dams and reservoirs keep its waters under human control. The lakeâs average depth is 8 to 10 feet, while the deep water in the bayou averages about 20 feet.
