2010 Map of Venado Creek East

About this map

Los Olmos Creek and Dolores Creek wind through this arid Webb County landscape, defining the hydrology of a region where water management is central to ranching operations. The map documents the infrastructure of these private holdings, including the Frank Nunley Lake Dam, which creates the substantial Frank Nunley Lake in the northeastern quadrant. To the west, the Martinena Ranch Lake Dam secures Martinena Ranch Lake, a vital water source for the surrounding terrain. These engineered water bodies, along with Venado Creek and the southern sweep of Carrizitos Creek, reveal how land use in this part of South Texas is intrinsically tied to the seasonal flow and storage of its drainage networks. The sparse road system and widely separated ranch landmarks illustrate the isolated, large-acreage character of the area during the early 21st century.
