The confluence of the Frio River and the Nueces River anchors this South Texas landscape, where the town of Three Rivers sits as a central hub of roads and water. The map documents a complex hydrology including Three Rivers Lake, Olds Slough, and Rock Quarry Br, alongside man-made developments like Choke Canyon Ests. North of the main settlement, the terrain shifts into Sinclair Hollow near the waters of Sinclair Lake and Yarbrough Lake.
