The Frio River serpentines through this portion of La Salle County, creating a complex network of waterways and drainage systems characteristic of the South Texas brush country. The landscape is defined by the winding course of Cayman Slough and its namesake, Cayman Lake, which sit at the heart of the region's hydrography. Several seasonal tributaries, including Ruiz Cr, Rock Cr, and Cibolo Cr, feed into the primary river system, illustrating the natural irrigation patterns of the South Texas Plains.
