2016 Map of Twin Valley NW

About this map

Lockhart Swamp dominates the eastern landscape of this section of the Red River Valley, where the boundary between Polk and Norman counties is defined by a rigid grid of rural roads. The terrain is characterized by a high water table and extensive drainage engineering, most notably seen in the channelized path of State Ditch Number Sixty-eight and the winding course of Spring Cr. This environment reflects the late-century reliance on sophisticated water management to maintain agricultural viability in the Minnesota prairie. The map detail highlights the intersection of natural wetland features and the strict Public Land Survey System, with numbered county roads like Co Rd 129 and Co Rd 3 providing the primary framework for the area's sparse residential and farming infrastructure.
