2019 Map of Biel Lake NE

About this map

The south Texas rangeland where Webb and Duval counties meet is defined by its seasonal drainage systems and a scattered network of rural ranch roads. Several significant watercourses, including Colmena Cr and Charamusca Cr, carve subtle paths across the landscape, illustrating the hydrology that governs life in this brush country. The map shows the intersection of local infrastructure and private landholdings, where routes like Pintas Adami N Rd and Ranch Rd 863 provide the primary access to the isolated ranching operations of the region. This 2019 survey documents the enduring spatial patterns of large-scale land use, marking the long-established boundary line between Webb Co and Duval Co as it runs north-to-south through the center of the terrain.
