2011 Map of Cornwell Reservoir

About this map

Cornwell Reservoir and its associated Cornwell Dam anchor the southern portion of this high plains landscape in Montana's Valley County. The terrain is defined by a dendritic network of drainage systems, where Wolf Creek, Crooked Creek, and Spring Creek carve paths through the open range. This 2011 survey reveals a workspace of livestock management and water conservation, evidenced by the numerous named water sources critical for ranching in an arid climate, such as Hunt Spring, Burke Spring, and Alkali Spring. Transportation is limited to functional routes like Cornwell Rd and the Jensen Trl, which navigate between the creek beds and the Maraschino Dam to the east. The map provides a detailed view of the West Fork Cherry Creek as it joins the larger drainage system, illustrating the vital role of these seasonal watercourses in the regional geography.
