2010 Map of Galvan Ranch

About this map

Galvan Ranch and Snakel Ranch anchor this landscape of the south Texas brush country, where isolated homesteads are linked by a network of ranch roads and tracks. The terrain is defined by a dendritic drainage system where intermittent waterways like Santa Isabel Creek, Tierra Blanca Creek, and Cuchara Creek carve through the arid Webb County plains. A notable human modification of the local hydrology is the Milstead Lake Dam on a tributary in the southern portion of the quadrangle. This 2010 survey reflects a period when traditional cattle ranching remained the primary land use, with many of the smaller labels denoting stock tanks and localized water improvements essential for livestock in this semi-arid environment. The mapping also details the drainage of Chalker Creek in the northeastern corner, illustrating the importance of natural watercourses in an otherwise dry landscape.
