2011 Map of Christmas Reservoir

About this map

Christmas Reservoir and the surrounding ranchlands of Valley County define this northern Montana landscape, where water management is central to the local geography. This survey documents a complex network of small reservoirs and earthen dams, including Pippin Reservoir, Far Nuff Reservoir, and Trailerhouse Reservoir, which capture seasonal runoff from the prairie. The drainages of Brazil Creek and Square Creek carve subtle paths through the terrain, joined by smaller coulees like Home Coulee and Road Coulee. The presence of the MRCLA Number 5 Dam and Alkali Dam highlights the long-standing efforts of the Milk River Co-operative Livestock Association and local ranchers to secure water for livestock in this semi-arid region. These named landmarks and water features provide essential points of reference for understanding land use and grazing patterns in the Missouri River watershed during the early 21st century.
