About this map

The Biel Oil Field dominates the southeastern portion of this South Texas landscape, where the extraction industry meets an arid network of ranchlands. Scattered Oil Wells and a Drill Hole point to the intensive exploration of the early 1970s, while numerous earthen catchments like Arrowhead Tank, Retama Tank, and Woodpecker Tank highlight the necessity of water management in Webb County.

Ephemeral drainage systems including San Casimiro Creek and Los Pintas Creek converge toward the reservoir at Biel Lake. Settlement is sparse and focused on established operations such as the Las Pintas Ranch and Welder Dobie Ranch, reflecting a long-standing pattern of large-scale cattle and resource holdings. The presence of a Gaging Sta along the creek indicates the careful monitoring of seasonal water flow through this brushland environment.
