2019 Map of McNary

About this map

Rio Grande defines the international boundary between the United States and Mexico, anchoring this arid landscape in Hudspeth County. The small settlement of McNary sits just north of the river, positioned near a network of irrigation and drainage features essential for desert agriculture. This hydrologic system includes the Wells Drain, Diablo Lateral, and Lower Drain, which redirect water across the valley floor. To the east, the Madden Ponding Area serves as a significant terrain feature alongside the Madden Drain and Algodon Lateral. Beyond the river valley, the topography rises toward higher ground, cut by the seasonal channel of Arroyo Diablo. The layout of these canals and laterals reveals the complex water management required to sustain life and farming in this borderland corridor.
