The convergence of the Frio River, Atascosa River, and Nueces River anchors this 1925 survey of Live Oak County, Texas. This hydrological junction shaped the early 20th-century development of Three Rivers and George West, which served as critical transportation hubs. The landscape is defined by a dense network of water features like Pugh Marsh and numerous hollows, such as Sinclair Hollow and Graveyard Hollow, which provided drainage across the varied elevations of Big Flat.
