1982 Map of Blocker Tank

About this map

The Chaparral Wildlife Management Area dominates the central portion of this South Texas landscape, straddling the boundary between Dimmit and La Salle counties. This arid brushland is defined by a critical network of water catchments, including Blocker Tank, Marrano Tank, and Baldy Tank, which were essential for ranching operations and wildlife survival in the semi-desert environment. The drainage of Sage Creek meanders across the territory, providing a natural corridor through the scrub.
