2011 Map of Ketchum Reservoir

About this map

Ketchum Ranch sits at the heart of this high-elevation landscape in north-central Oregon, where the headwaters of numerous creeks carve through the ridges. The terrain is defined by prominent basaltic features and flats, including Woods Backbone, Smith Ridge, and Breeds Flat. Water management is central to the area's history, evidenced by Ketchum Reservoir and its associated Ketchum Dam, along with several livestock-oriented basins like Sky Ranch Reservoir Number Three. Numerous named springs, such as Old Schoolhouse Spring and Schoolman Spring, point to the essential water sources that sustained early settlers and ranchers in this arid backcountry. The map also traces a network of timber and ranch roads, including Hedges Grade and Mill Creek Rd, which navigate the complex drainage systems of Mosier Creek and North Fork Mill Creek.
