1985 Map of Sandpiper Reservoir

About this map

Sandpiper Reservoir and a network of seasonal water management sites define this part of Blaine County as it appeared in the mid-1980s. The landscape is heavily marked by the drainage patterns of deep coulees, including Bullwhacker Coulee and Davidson Coulee, which dictate the local topography. A notable point of historical interest is Coal Mine Branch, a tributary name that suggests the area's geological and perhaps early industrial past. Smaller impoundments like Blanch Reservoir, Bud Reservoir, and Brush Shack Reservoir are scattered across the terrain, highlighting the critical importance of water storage in this arid Montana environment. The lack of major paved roads on this 1985 provisional survey emphasizes the rural and working-land character of the region during this era.
