Negro Gap and the surrounding drainage basins of the San Saba River watershed define this rural landscape on the border of Concho and Menard Counties. This mid-2010s survey reveals a territory dominated by seasonal watercourses and conservation efforts, most notably the Soil Conservation Service Site 29 Reservoir in the north. The area is characterized by a sparse network of ranch roads and family-named thoroughfares like Wilhelm Ln and Waddell Ln that navigate the undulating terrain. A distinct geographic feature, the Arroyo de Juan Lorenzo, cuts through the central hills, feeding into a system of creeks including Live Oak Cr, Fitzgerald Cr, and Celery Cr. This map is particularly useful for understanding the modern hydrologic management and property divisions in this portion of the Edwards Plateau.
