2022 Map of School Grove Lake
USGS Topo · Published 2022About this map
School Grove Lake and Timm Lake define the central landscape of this western Minnesota prairie region, situated at the intersection of Lyon, Redwood, and Yellow Medicine counties. The map captures a largely agricultural expanse where natural hydrology has been significantly modified over time, evidenced by the large footprints of Twin Lake Bed and Goose Lake Bed. These former lake basins, along with an extensive network of drainage infrastructure like Judicial Ditch Number Three and County Ditch Number Forty-six, reflect the historical effort to manage the high water table for productive farming.
