Green Valley serves as a central point in this part of Lyon County, where the agricultural landscape is defined by an extensive network of managed waterways. The drainage patterns are clearly visible through engineered features like County Ditch Number Fifteen and County Ditch Number Nineteen, which support the productivity of the surrounding prairie. Natural watercourses also meander through the townships, including the Yellow Medicine River in the northwest and the Redwood River in the southeast. This modern survey reflects the enduring grid system of the Public Land Survey System, with roads like CO Hwy 19 and CO Hwy 8 following township and range lines. For those exploring the riverbanks, the Redwood River Trl provides a trace of the local recreation paths near Threemile Cr.
