The settlement of Mayoworth sits at the center of an intricate irrigation network in Johnson County, where the High Plains meet the eastern slopes of the Bighorn Mountains. Water management is the primary human imprint on this landscape, visible through the complex system of the Morgareidge Ditch, Barrett Ditch, Capitola Ditch, and Strickler-Rinker-Ditch, which divert the flows of the N Fork Powder River and its tributaries to support local ranching.
