The Frio River carves a winding path across this South Texas landscape, defining the transition between Frio and La Salle counties. This 2022 survey documents a largely agricultural and ranching corridor where the river is fed by several tributaries, including Lockhardt Cr from the north and Martin Br and Martin Branch from the west. The presence of Burns Reservoir indicates the critical importance of water management and storage in this arid environment.
