About this map

Dog Creek Detention Reservoir and a sophisticated network of water management features dominate this portion of the Montana prairie in the mid-1980s. The landscape is defined by the strategic containment of seasonal flows through many earthen works, including the Bomber Detention Diversion Dam and the Pearson Detention Dam. These structures served the vital ranching interests of Valley County, creating essential water sources like Salty Glen Reservoir, Snow Blind Reservoir, and Lori Detention Reservoir.

Physical landmarks such as Two Buttes and the open expanse of Cactus Flat provide navigational anchors in an otherwise rolling terrain. The presence of specialized basins like Skeeter Detention Reservoir and Target Detention Reservoir illustrates the engineered approach to land use in this arid environment. This provisional survey captures the intersection of hydraulic engineering and traditional livestock grazing before modern shifts in land management.
