2011 Map of Sourdough Spring
USGS Topo · Published 2011About this map
Sourdough Mountain and Grassy Mountain anchor this high-desert landscape in southeastern Malheur County. The terrain is defined by a critical network of water sources essential for livestock and local wildlife, including Freezeout Lake and numerous developed catchments like Upper Kane Spring Reservoir, Poison Spring Reservoir, and Grassy Reservoir. These man-made features, interspersed with natural draws such as Basin Gulch and Wildcat Canyon, illustrate the region's long-standing reliance on carefully managed water rights.
