2016 Map of Gillis Ranch

About this map

Gillis Ranch and the rugged canyonlands of Val Verde County dominate this 2016 topographic study. The landscape is defined by the winding course of the Devils River as it flows south toward the Amistad National Recreation Area. This arid terrain is marked by significant drainages and water features, including the seasonal flows of Dead Mans Cr, Little Satan Cr, and Evans Cr. High-ground relief is punctuated by landmarks such as Dark Canyon and Gillis Springs. Human impact remains sparse and ranch-focused, centered on private holdings and the infrastructure of Wardlaw Ranch Rd. The presence of Gillis East Lake and Gillis West Lake highlights the importance of water management in this western Texas environment, while the northern reaches of Walk Lake signal the transition into federally managed recreational lands along the river corridor.
