About this map

The divide between Comanche Co and Brown Co marks the western edge of this 2016 topographical landscape. Defined by the breaks of the Lampasas Cut Plain, the terrain is anchored by two prominent natural passes: Cox Gap and Mercers Gap. The drainage patterns here are complex, with the headwaters of Mercer Cr and Moore Cr carving through the limestone hills, while Dry Blanket Cr winds southward toward the Leon River.

Modern water management is a central feature of the landscape, evidenced by a series of structured reservoirs including Soil Conservation Service Site 12 Reservoir, Soil Conservation Service Site 13 Reservoir, and Soil Conservation Service Site 14 Reservoir. These engineered sites, alongside Lake Eanes and Willis Lake, reflect the region's 20th-century focus on flood control and ranching sustainability. The map also traces an extensive network of rural routes, from Ranch Rd 590 to numerous county roads that follow the contours of the Texas backcountry.
