2023 Map of Tumtum Lake

About this map

Tumtum Lake sits as the central hydrologic feature of this high desert landscape, where the flat basins of Alvord Valley and Pueblo Valley meet the rising elevations of the White Horse Mountains. This remote corner of Harney County is defined by its drainage systems, with Trout Creek and Willow Creek descending from the highlands into the arid valley floors. The map details the transition from the steep contours of Snake Den Butte to the broad, open stretches of the southern Oregon sagebrush steppe.
