Rio Grande defines the international boundary between Maverick County, Texas, and the Mexican state of Coahuila in this 21st-century survey. The landscape is primarily a drainage basin for numerous tributaries flowing toward the border, including Pinto Creek, Goat Creek, and Derramadero Creek. Human presence is largely defined by ranching infrastructure and private aviation, centered around the Frerich Ranch Airport and nearby water management features like Frerich Lake Number 1 Dam and Frerich Lake Number 2 Dam.
