2017 Map of Tumtum Lake

About this map

Tumtum Lake and the marshy expanses of Pueblo Slough anchor the southern reach of this high-desert landscape in Harney County. The terrain transitions from the floor of the Pueblo Valley and Alvord Valley into the steep rises of the White Horse Mountains to the east and the prominent Snake Den Butte in the west. This 2017 survey details a network of drainage systems essential to this arid environment, including Trout Cr, Willow Cr, and Little Cottonwood Cr. The map documents the modern infrastructure of the region through corridors like Fields Dr and Whitehorse Ranch Rd, which connect the scattered ranching interests and water sources. The presence of numerous seasonal creek beds and springs, such as Spring Cr, underscores the hydrological patterns of this remote interior basin.
