2017 Map of Dubbe Reservoir

About this map

Johnson Coulee dominates the northern reaches of this Valley County landscape, illustrating the intricate drainage patterns that define this section of the Frazer District. The terrain is characterized by a network of intermittent watercourses, including the southward-reaching Little Porcupine Cr and the eastern flow of Oswego Cr. The map reveals human efforts to manage these seasonal waters through the construction of landmarks like Horgan Reservoir and the namesake Dubbe Reservoir in the southeast. While largely an open range, the presence of W Granada Rd and a grid of township boundaries, such as t28n r44e, provides the necessary structure for land management and navigation within this rural Montana expanse.
