2020 Map of Dayville

About this map

The settlement of Dayville sits at the confluence of the John Day River and the S Fork John Day River, serving as a central hub for the surrounding ranching and wilderness areas. This modern survey illustrates the complex water management of the region, featuring irrigation infrastructure like Throop Ditch and Cummings Ditch alongside several small upland catchments such as Nash Reservoir and Conner Cr Reservoir. The northern boundary includes a portion of the John Day Fossil Beds National Monument, while the southern reaches extend into the Ochoco National Forest. Genealogical interest centers on the Dayville Cem located north of the townsite. The terrain is marked by numerous named basins and springs, including McNulty Basin and Fort Basin Springs, indicating a landscape where water sources dictate both natural features and human habitation patterns.
