2020 Map of Blizzard Reservoir

About this map

Blizzard Reservoir and the adjacent Big Snowy Reservoir anchor this section of Phillips County, where the landscape is defined by the intricate drainage patterns of the Missouri River watershed. The terrain is deeply incised by Nichols Coulee and several seasonal watercourses, including the winding paths of Sevenmile Creek and Spring Creek. These catchments and coulees are central to the region's ranching and land management history, reflecting the necessary infrastructure for water storage in this semi-arid environment. The map details the Public Land Survey System grid across portions of Township 23 North, Range 26 East and neighboring ranges, showing the administrative framework that governs this rural Montana expanse. The sparse distribution of named features underscores the open, undeveloped character of the territory, where geography is dominated by natural landforms rather than dense settlement.
