2016 Map of Biel Lake NE

About this map

The boundary between Webb Co and Duval Co divides this South Texas landscape, defined by a network of drainage channels and ranch access roads. The ephemeral waters of Colmena Cr, Charamusca Cr, and Black Cr pattern the terrain, reflecting the arid environment of the Brush Country. Transportation through this remote section of the county is anchored by Ranch Rd 863, which cuts across the central portion of the map, and Pintas Adami N Rd in the northwest. These routes, along with Co Rd 401, provide the primary infrastructure for the area's large-scale ranching operations, showing how modern land use still follows the contours of the historic Texas cattle country.
