Showing Cross Lake in Shreveport at the bottom of this map.  The Louisiana portion of the Sodo Lake complex, as reconstructed by Arthur Vetch from 1839 Louisiana State Survey maps.  By 1839 the lakes had been differentiated, with Caddo Lake bearing the name Ferry Lake, and Sodo Lake being called by the name of the complex.  Shiftail Lake was the northeast extension of Sodo Lake on this map.
