2010 Map of Black Waterhole

About this map

The West Nueces River carves a winding path through this portion of Edwards County, defining a landscape of complex drainage systems and intermittent watercourses. In this arid reach of West Texas, the presence of Silman Spring stands as a critical water source for local ranching and wildlife. The map captures the intricate topography of the Edwards Plateau, where numerous named ravines like Crooked Draw, Cedar Draw, and Little Hackberry Draw funnel seasonal runoff toward the primary river valley. High ground is marked by features such as Jackson Flat, while transportation across the limestone terrain is facilitated by Ranch Rd 674 and Co Rd 14. This survey offers a precise record of the regional hydrography, including Geronimo Creek and Possum Creek, as they appeared at the start of the 21st century.
