2019 Map of Dull

About this map

Dull stands as the primary namesake settlement in this arid reach of La Salle County, where the landscape is defined by its seasonal water sources and ranching infrastructure. The Frio River and Cayman Slough provide the major drainage patterns in the northeast, while the rest of the terrain is marked by an extensive system of man-made tanks, such as TCU Tank, Quintana Tank, and Salt Well Tank. These features, along with names like Rock Hill Tank and Northeast Yeager Tank, underscore the critical importance of water management for cattle operations in South Texas. Crossing the center of the sheet, the expansive Dull Flats transition into drainages for Cibolo Cr and Yeager Cr, reflecting the topographic character of the Brush Country. Rural routes like El Jardin RD and Koon Hill Rd connect these remote points across a largely open landscape.
