2020 Map of Collins Reservoir

About this map

Mosquito Reservoir and a high density of small water catchments characterize this portion of Valley County, Montana. The landscape is defined by the repetitive drainage patterns of Lone Tree Creek and Short Creek, which feed into numerous named reservoirs such as Beast Reservoir, Skull Reservoir, and Tuna Reservoir. This pattern of water management suggests a landscape heavily adapted for livestock grazing or local agriculture in an arid environment. Movement through this section of the Missouri River basin is facilitated by specific access routes like the Triple Cross Access Rd and Willow Creek Rd, which navigate the various coulees including Pearson Coulee and Roosevelt Coulee. The naming conventions found here, from Your Name Reservoir to Bones Reservoir, provide a distinct sense of the local geographic identity at the time of this 2020 survey.
