1984 Map of East Losa Tank

About this map

San Lorenzo Creek defines the drainage of this arid landscape along the Dimmit Co Webb Co border during the mid-1980s. The map reveals an environment engineered for ranching and resource extraction, characterized by an extensive network of water tanks and windmills essential for livestock. Notable catchments like East Losa Tank, South Losa Tank, and the Palo Blanco Tank are scattered across the terrain, often accompanied by mechanical lifelines such as the Losa Windmill and Toro Windmill. An Indefinite Boundary cuts through the center of the sheet, while scattered Oil Wells and a Gravel Pit indicate the industrial footprint of the era. The presence of several Wells and smaller tanks like Javelina Tank and Ojita Tank further illustrates the critical importance of water management in this South Texas borderland region.
