About this map

Yonna and Hildebrand stand as the primary settlements within the broad agricultural expanse of the Yonna Valley during the late 1980s. The landscape is defined by its water management systems, featuring a network of drainage and storage including the Ritter Reservoir, Horton Reservoir, and Cox Reservoir. These man-made features contrast with natural hydrology like Johnny Lake and Log Lake, illustrating the transformation of the high desert terrain for ranching and farming.

Elevated terrain surrounds the valley, with Bly Mountain rising to the northeast and Short Lake Mountain to the south. The area transitions into the timbered slopes of the Winema National Forest, where features like Bly Mtn Pass and the Klamath Falls Lakeview Wayside State Park indicate the intersection of transportation and conservation. Springs such as Boundary Spring and Indian Spring remain vital markers of the area's natural geography.
