2022 Map of Venado Creek East

About this map

Los Olmos Cr and its tributaries carve through this section of Webb County, defining a landscape of intermittent drainages and ranchland reservoirs. Water management is a central theme of this terrain, anchored by Frank Nunley Lake in the north and the Martinena Ranch Lake further south. These catchments, along with named watercourses like Dolores Cr and Carrizitos Cr, are vital for the cattle ranching operations that have long characterized this region of South Texas. In the northeast corner, Ranch Rd 863 provides the primary corridor for modern transit through the brush country. The map captures the complex system of creeks, including Venado Cr, illustrating how the drainage network supports isolated ranching infrastructure far from the more densely populated areas of the Rio Grande valley.
