2024 Map of Lake Abert South

About this map

The towering Abert Rim dominates this section of south-central Oregon, dropping sharply toward the expansive, saline waters of Lake Abert to the west. This landscape illustrates the dramatic Great Basin geology, where a massive fault scarp creates a vertical wall of basalt that separates the high plateau from the alkali lake below. The eastern portion of the map reveals a series of critical high-desert water sources, including Sheep Creek Spring and Webb Springs, which feed into complex drainages like Mule Draw. Local ranchers and land managers have modified this environment with features such as Spawn Reservoir and the Lower Basin Draw Reservoir, alongside various named stock tanks like Juniper Waterhole. These features highlight the ongoing efforts to manage water for livestock and wildlife across this arid, high-elevation terrain.
