About this map

Willow Creek Reservoir dominates the center of this Montana landscape, where intricate water management systems define the local geography. The Willow Creek Dam regulates the reservoir, feeding into a network of irrigation works including the Kirkaldie Canal and Floweree Canal. This 2011 survey reveals a heavily engineered environment where even small tributaries are managed by structures like Peach Fuzz Dam, Gordan Lightfoot Dam, and Young Sun Dam.

To the south, the settlement at Split Rock Junction sits near the base of Carey Butte, overlooking the expansive Kirkaldie Flats. The map documents a transition from these open flats toward the northern reaches of the Sun River, where the Sun River Slope Canal parallels the river course. The residential grid north of the reservoir, featuring names like Ponderosa Dr and Cottonwood Dr, indicates a pocket of development amidst the broader agricultural and hydraulic infrastructure.
