1980 Map of Hay Lake

About this map

Egli Ridge and the high terrain of Sheep Mountain dominate this corner of Harney County, characterized by a complex network of water management features essential for high-desert ranching. Surveyed in the mid-1970s, the landscape reveals the survival of early settler footprints through labels like the Old Egli Place and the Harry Arnold Ranch. These homesteads are supported by a wide array of catchment systems, including the Egli Reservoir, Egli Waterhole, and Spring Canyon Reservoir. The northeastern portion of the map includes a section of the Squaw Butte Experiment Station, indicating the region's importance for agricultural research. Geologic and natural curiosities are also present, such as the distinctive Hole in Ground and various seasonal water bodies like Rimrock Lake and Ryegrass Lake.
