About this map

Dull and the nearby Dull Flats occupy a landscape defined by an extensive network of water management features and intermittent drainage in La Salle County. The terrain is marked by numerous stock tanks and reservoirs essential for ranching in this part of South Texas, including Cibolo Tank, Quintana Tank, and Rock Hill Tank. Water resources are further managed by engineered structures like the Donnell Lake Dam and Kenley Lake Dam.

The settlement of Los Angeles sits in the western portion of the map, connected to the surrounding area by roads such as El Jardin Rd and Koon Hill Rd. This network links the various ranching outposts to the Frio River and Cibolo Creek, which serve as the primary natural drainage systems. The presence of Cayman Slough and McGraw Lake highlights the localized depressions and riparian zones that punctuate the arid brushland.
