2024 Map of McHan Reservoir

About this map

The Mount Bennett Hills dominate the southern portion of this landscape, where the Camas Co Gooding Co line divides the high-country drainage basins. The area is defined by a dense network of seasonal and perennial waters, including the headwaters of Spring Creek and McKinney Creek in the north, and the deep incisions of Black Canyon Creek and Thorn Creek to the south. Historically significant water sources like Bull Spring, Hash Spring, and Gwin Spring are scattered across the terrain, indicating the vital importance of reliable water in this high-desert environment. Notable landmarks such as Flat Top Butte and Johnson Hill provide vertical relief above Burnt Willow Canyon and Long Gulch. The sparse road network, centered on Fir Grove Rd, highlights the remote character of this region on the border of Camas and Gooding counties.
