2019 Map of San Miguel Ranch

About this map

The San Miguel Ranch sits at the heart of this South Texas landscape, where the border between Atascosa and McMullen counties is defined by a straight survey line cutting through rolling drainage basins. This area is characterized by an extensive network of seasonal and perennial waterways that feed into San Miguel Cr, which snakes across the southern portion of the sheet. Ranching operations are central to the landscape, evidenced by the El Tesoro Ranch Airport and significant water management features like Hindes Lake and T H Cattle Company Lake. The road network, including Co RD 3455 and Hinsley Ranch Rd, provides access to these isolated holdings. Small private reservoirs such as Erwin Lake illustrate the critical importance of water storage for livestock in this semi-arid environment.
