1971 Map of Knippa

Water is a vital resource in this semi-arid region, with the Frio River and the Dry Frio River carving through the eastern half of the map while the Leona River defines the western edge. Notable landmarks such as Black Waterhole and various drainages like Taylor Slough and Salt Creek indicate the seasonal nature of local hydrology. The presence of a Radio Tower and numerous gravel pits suggests the local economy's reliance on both modern communication infrastructure and traditional resource extraction.
