1987 Map of Mann Creek NW

About this map

The Payette National Forest dominates the northern reaches of this Washington County landscape, where the high country gives way to a network of drainage basins. Central to the area's geography is the Mann Creek Reservoir, an engineered water body held by the Mann Creek Dam. This reservoir and the smaller Fairchild Reservoir to the north indicate the critical importance of water management in this part of Idaho, serving as vital infrastructure for the surrounding terrain.
