About this map

Briscoes Catarina Ranch Airport and a series of managed water resources define this ranching landscape in Webb County during the early 21st century. The map reveals a complex system of livestock infrastructure and water management, centered on the Espejo Ranch and Brown Ranch properties. Significant engineering is evident through numerous named impoundments such as the Dolph Briscoe Lake Number 7 Dam, Dolph Briscoe Lake Number 6 Dam, and Gates Lake Dam, which capture seasonal flows from drainage systems like Bonito Creek and the Espejo watercourse. The network of rural routes, including FM 2688 and RD 5004, provides the primary access through this sparse, industrial ranching terrain, illustrating how modern land use in South Texas adapts to a semi-arid environment through extensive water catchment and private aviation.
