About this map

Johnson Reservoir sits at the heart of this Dawson County landscape, serving as a primary water source in an area defined by the branching drainage of Deer Creek. The terrain is deeply etched by the N Fork Deer Cr, Middle Fork Deer Cr, and S Fork Deer Cr, which together form a complex hydraulic network across the rangeland. In the northeast corner, Lower Sevenmile Cr cuts across the township boundary of T19N R53E, further illustrating the importance of natural drainage in this part of Montana.

Transportation in this rural expanse is dictated by a grid of section-line roads, including Rd 442, Rd 435, and Rd 454. These routes, along with utility corridors like Aeaf 15-N, provide the infrastructure for local agriculture and land management. The 2017 survey reflects a largely undeveloped landscape where the intersection of water rights and public land surveys remains the dominant geographical feature.
