About this map

The Choke Canyon Reservoir dominates the southern landscape of this South Texas region, where the Frio River and several drainages converge at the borders of McMullen, Atascosa, and Live Oak Counties. This 2022 survey captures the modern topography of a sparsely populated ranching and water-management landscape defined by named landforms like Opossum Hill and a series of drainage basins including Ursher Hollow and Prairie Hollow.

In the northern reaches, the Atascosa River winds through the terrain near Olmos Cr, while a network of secondary roads such as FM 99 and Co RD 417 provides access to private lands and livestock water sources like the Willow Hollow Tank. The map serves as a contemporary record of the hydrologic features and property divisions in this brush-country environment, tracing the flow of Comanche Br and Opossum Cr toward the reservoir.
