2020 Map of Diatomite Reservoir

About this map

Saunders Rim dominates the northern landscape of this Lake County terrain, where the high-desert topography of south-central Oregon is defined by subtle elevation shifts and essential water sources. In an arid region where geography often dictates survival and land use, features like Sammys Horse Pen Waterhole and Camp Tank Waterhole serve as critical landmarks for ranchers and land managers. The southern portion of the quadrangle is marked by the distinct formation of Twin Buttes, providing a clear visual anchor in an area otherwise characterized by vast open stretches. This 2020 data captures the contemporary survey boundaries of Townships 30 and 31 South, reflecting the enduring grid system that manages this sparse but significant landscape.
