About this map

Dayville serves as the focal point of this Eastern Oregon landscape, situated at the confluence where the South Fork John Day River meets the main John Day River. The town's layout is centered near the Dayville Post Office and along Ervin St, with the Dayville Cemetery overlooking the river valley to the west. This 2011 survey reveals an environment defined by water management and ranching, evidenced by features such as Dexter Ranch and the historical irrigation infrastructure of Cummings Ditch and Throop Ditch.

Beyond the river bottom, the terrain climbs toward prominent landmarks like Table Rock and Bottle Rock. The map documents numerous named springs and basins, including Fort Basin Springs and McIntire Basin, which support the high-desert livestock operations. To the south and west, the landscape becomes increasingly complex as drainage systems like Battle Creek flow toward the Mountain Reservoir, illustrating the geographic transition from the river valley to the more isolated upland basins of Grant County.
