Dayville serves as the focal point of this Grant County landscape, situated at the confluence of the John Day River and the S Fork John Day River. The geography is defined by a series of high-elevation basins and gulches, including McNulty Basin and Guyon Basin, which provide a complex network of drainage for the high desert terrain. Local water management is evident through features like the S Fork Cummings Ditch and the Nash Reservoir, reflecting the long-standing agricultural and ranching requirements of the region.
