2014 Map of Seymour Reservoir

About this map

Rudolph Valley defines the northern reaches of this Phillips County landscape, where the prairie is carved by a network of drainage features. Water management is central to the area's geography, anchored by the Seymour Reservoir in the northeast and Bass Reservoir further south. These catchments, along with named drainages like Big Warm Cr and Wild Horse Cr, indicate the vital importance of water storage in this high plains environment. The terrain is further characterized by deep incisions such as North Fork White Rock Coulee and Lonesome Coulee. Local transportation is limited to established routes like Midale Rd and Ereaux Rd, which provide access through the vast grazing lands of north-central Montana.
