The Missouri River carves a deep path through this mid-century landscape, serving as the central artery for a complex system of industrial and agricultural infrastructure. Near the settlement of Toston, the river's power is managed by the Toston Dam, which feeds an extensive irrigation network including the Toston Canal and Lombard Canal. This infrastructure was vital for the area's development, as evidenced by the engineering noted at Toston Tunnel and the nearby Siphon.
