The watershed of Tortuga Cr and its eastern branch dominates this portion of Zavala County, where the landscape is defined by an extensive network of water management features. This cattle-country terrain is punctuated by dozens of named tanks, reflecting the vital importance of water storage in this semi-arid region. Notable landmarks such as Headquarters Tank, Lost Waterhole Tank, and Windmill Tank suggest the operational hubs of large ranching estates.
