The Frio River and Leona River converge in this South Texas landscape, defining a region where water management and energy extraction are central to the terrain. The settlement of Derby sits at the southeastern edge of the map, adjacent to the transportation corridor of Hwy-81. This 2013 survey illustrates the continued importance of livestock and resource infrastructure, evidenced by a dense network of family-named and descriptive water sources such as Honeymoon Windmill, Round Mountain Windmill, and Abispa Windmill.
