2022 Map of San Miguel Ranch

About this map

The south Texas ranching landscape along the border of Atascosa and McMullen counties is defined by a dense network of intermittent drainages and livestock-focused water improvements. The San Miguel Cr and its tributaries, including Lagunillas Cr and Raccoon Cr, carve through the brush country, creating a complex hydrologic pattern that dictated early settlement and land use. Small reservoirs and catchments are vital landmarks here, such as Hindes Lake, Erwin Lake, and T H Cattle Company Lake, serving the region's large cattle operations. Aviation infrastructure is represented by the El Tesoro Ranch Airport, located just north of Hinsley Ranch Rd. The map illustrates the sparse, high-acreage development characteristic of the region, where connectivity relies on local routes like Co RD 343 and Yeager Rd.
