About this map

The Frio River and a network of seasonal watercourses define the landscape of northern McMullen County in the early 21st century. This region of South Texas is characterized by ranching infrastructure and energy extraction, as seen in the extensive Dragoon Oil and Gas Field that occupies the southern portion of the survey. The terrain is marked by numerous small bodies of water, including Yarbrough Lake, Whitmire Lake, and Singer Lake, which serve as vital water sources in this semi-arid environment.

Transportation is facilitated by a grid of county roads and larger arteries such as Ranch Road 99 and Rec Road 7. Named landmarks like Bracken Ranch Lake indicate the legacy of large landholdings in the area. Numerous drainages, including Dragoon Cr, Salt Cr, and Paisano Cr, carve across the plains toward the Frio, illustrating the local hydrology and watershed patterns essential for both cattle ranching and resource management.
