2016 Map of Black Waterhole
USGS Topo · Published 2016About this map
The W Nueces River carves a complex drainage network through this portion of Edwards County, where the dry-wash topography is defined by seasonal draws and isolated water sources. The namesake Black Waterhole and Silman Spring serve as critical hydrological markers in an arid landscape dominated by the winding course of Geronimo Cr and Possum Cr. This 2016 survey captures the intersection of modern transit and older routes, showing where Ranch Rd 674 and Old US Hwy 377 navigate the terrain.
