2013 Map of Mann Creek NW

About this map

The northern boundary of the Payette National Forest dominates this section of Washington County, where the high drainage divide separates numerous vital water sources. The landscape is defined by the headwaters of Mann Creek and its southern neighbor, the Mann Creek Reservoir, which provide essential water management for the region. To the west, the terrain slopes toward Monroe Creek and Jenkins Creek, revealing the intricate network of canyons and ridges that characterizes this part of Idaho. Rural access is maintained via historically significant routes like Deer Creek Road and Sage Creek Road. This 2013 survey illustrates how forest management boundaries and water infrastructure, such as the Fairchild Reservoir, continue to shape the geography of these western uplands.
