2024 Map of Seymour Reservoir

About this map

Rudolph Valley and the surrounding high plains of Phillips County define this 2024 topographic landscape. The map detail centers on water management and drainage across a sparsely populated region, anchored by Seymour Reservoir and Bass Reservoir. These catchments are vital to the local ranching economy, where seasonal water flow is managed through the winding course of Big Warm Creek. The terrain is deeply carved by numerous drainages, including the North Fork White Rock Coulee and Lonesome Coulee, showing the complex erosion patterns characteristic of the Montana plains. Access to these remote sections is maintained by a network of rural routes such as Midale Rd and the White Rock Access Rd, which serve the large townships and range blocks of this northern territory.
