2022 Map of Edgemon Lake

About this map

Edgemon Lake and Emerson Lake sit at the heart of this landscape, marking a transition between the high plains and the complex drainage systems of the Caprock escarpment. The topography is defined by deep incisions such as Dark Canyon and Pole Canyon, which channel water toward the Los Lingos Cr system. This 2022 survey captures a remote section of the Texas Panhandle where the boundary between Briscoe and Floyd counties cuts through a series of dramatic landforms, including Dobbs Hollow and Long Hollow. These natural catchments and springs, like Red Rock Spring, have historically dictated the placement of ranch roads and water management in this arid environment. The map details a network of rural routes, including FM 689, that connect the isolated water bodies of Grahams Lake and Cottonwood Lake to the broader regional grid.
