Dubbe Reservoir and the surrounding high plains of Valley County define this northern Montana landscape. The area is characterized by a complex network of seasonal drainages and coulees, most notably Johnson Coulee and Oswego Creek. These waterways provide essential catchment in an arid environment, supporting small-scale water management infrastructure such as Horgan Reservoir and Structure Number 143 Reservoir.
