2020 Map of Ketchum Reservoir

About this map

The boundary between Hood River and Wasco counties cuts through this high-elevation terrain, where water sources were critical for early mountain settlement and grazing. Evidence of former community infrastructure appears at Old Schoolhouse Spring, a site hinting at the remote education once necessary in these hills. The landscape is defined by its drainages, including the headwaters of Mosier Cr and W Fork Mosier Cr, which descend from high ridges like Woods Backbone and Mill Creek Ridge.
