Blancas Cr and Dolores Cr carve through the dry landscape of the South Texas brush country along the border of Webb and Zapata counties. This 2019 survey documents a region primarily defined by extensive ranching operations and a network of private and county roads. The drainage systems, including the seasonally active El Jaral Cr, dominate the topography, illustrating the natural watercourses that define property boundaries and land use in this arid environment. Significant water management for livestock is evident at La Perla Ranch Lake Number 1 in the southwest. A grid of thoroughfares like Mangana-Hein Rd and several numbered branches of Ranch Road 7918 provide the primary access to these remote ranching tracts.
