2011 Map of Collins Reservoir

About this map

Collins Ranch serves as a primary landmark in this ranchland region of Valley County, characterized by an extensive system of small-scale water management. The landscape is defined by dozens of local impoundments such as Mosquito Reservoir, Skull Reservoir, and the centrally located Collins Reservoir. These numerous named catchments and dams, including the distinctively titled Thingamajig Dam and Gutshot Dam, reveal the essential infrastructure required to support livestock and agriculture in this dry Montana climate. Natural drainages like Lone Tree Creek and South Fork Beaver Creek dictate the placement of these reservoirs. The road network, featuring Triple Cross Access Rd and Willow Creek Rd, connects these isolated water sources and ranching outposts, illustrating the sparse but organized settlement pattern of the early 21st century.
