About this map

Dewey Lake and its surrounding drainage systems define the heart of this Glasscock County landscape. The map captures a complex network of intermittent water features, where the broad basin of the lake is fed by Meyers Draw and Thirtysix Draw. This hydrological pattern, including a distinctive terrain feature known as The Neck, illustrates how water moves through this semi-arid region of the Llano Estacado.

Ephemeral lakes and stock tanks, such as White Lake, Salt Lake, Bluebell Tank, and Big Tank, are scattered across the quadrangle, indicating the area's pastoral reliance on captured surface water. Long drainage paths like Mustang Draw and Johnson Draw cut across the contours, showing the natural relief of a landscape shaped by seasonal runoff. Apart from Co RD 455, the area remains dominated by these geographic markers and the infrastructure of ranching and resource management.
