2019 Map of Green Valley

About this map

Green Valley serves as the central focal point of this agricultural landscape in Lyon County, where the grid of rural section roads meets an intricate network of natural and engineered waterways. The southern portion of the quadrangle is defined by the Redwood River, while the northern reaches include the headwaters or tributaries of the Yellow Medicine River. This 2019 survey illustrates the heavy reliance on sophisticated drainage systems to manage the fertile prairie soils, featuring prominent infrastructure such as County Ditch Number Fifteen, County Ditch Number Nineteen, and County Ditch Number Thirtytwo. These channels, alongside natural features like Threemile Cr, dictate the movement of water across a terrain dominated by section lines like Co Hwy 19 and Co Hwy 8. The map documents a contemporary rural Minnesota environment where the legacy of the Public Land Survey System remains the defining structure for settlement and agriculture.
