About this map

Turnbull Island dominates this deltaic landscape where the Red River and Mississippi River converge amidst a complex system of historic channels and bayous. The map documents a pivotal hydrological area at the meeting of Concordia, Avoyelles, West Feliciana, and Pointe Coupee parishes. Significant water management features are evident, including the massive Outflow Channel and various segments of the Upper Old River and Old River, illustrating the engineered efforts to control the shifting courses of these major southern waterways.
