About this map

The North Fork Clearwater River Reservoir, also identified as the Dworshak Reservoir, dominates the northern landscape of this Clearwater County region. Reaching a normal pool elevation of 1600 feet, the water fills a network of drainages including Whiskey Creek, Larkins Creek, and Long Bar Creek. This 1981 survey illustrates the interface between the reservoir and the surrounding Clearwater National Forest and St Joe National Forest.

The terrain is defined by high peaks and strategic saddles, most notably Bertha Hill and Benton Butte, which is topped by a Lookout Tower. Historical land use is evidenced by several 4WD tracks and remote clearings such as Camp 11. Topographic features like Cougar Rock, Black Bear Saddle, and Township Saddle provide essential landmarks for navigating the steep drainages of Thunder Creek and Ahlvers Creek south of the main reservoir.
