2019 Map of Gillis Ranch

About this map

Gillis Ranch serves as the central hub of this arid Val Verde County landscape, where water sources dictate the patterns of human settlement and land use. The presence of Gillis East Lake, Gillis West Lake, and the nearby Gillis Springs highlights the vital importance of these hydrologic features in a region defined by complex drainage networks. To the east, the Devils River carves a deep path through the limestone, its banks partly protected within the Amistad National Recreation Area. The topography is a maze of canyons and draws, including the sharply defined Dark Canyon and Dead Mans Cr in the north. Grounded by ranching history, the map shows how local infrastructure like Wardlaw Ranch Rd navigates the difficult terrain between Evans Cr and the river breaks.
