2010 Map of McNary

About this map

The Rio Grande defines the international boundary between the United States of America and Estados Unidos Mexicanos, anchoring a landscape shaped by water management and transit. In this borderland region, the settlement of McNary sits near the northern edge of the map, while Bayers Crossing marks a point along the river's path. The area is heavily defined by irrigation and drainage infrastructure essential for agriculture in this arid environment, featuring the Madden Drain, Lower Drain, and the Algodon Lateral. Local hydrology is managed through the Madden Ponding Area and Madden Lake Dam, which capture runoff from terrain features like Arroyo Diablo and Madden Arroyo. This 2010 survey illustrates the modern intersection of historic river geography and the structured engineering of the Madden Lateral and other waterways that sustain the border valley.
