About this map

School Grove Lake and a series of seasonal basins define this agricultural pocket of Lyon County. The landscape is marked by the transition of water into tillable land, seen clearly in the labeling of the Twin Lake Bed and Goose Lake Bed. This drainage is managed by a network of engineered waterways, including Judicial Ditch Number Three and County Ditch Number Ninetytwo, which redirect runoff toward the Redwood River in the south.

While the region is primarily defined by its section-line roads like 330th St and County Hwy-46, several named bodies of water remain significant landmarks, notably Tyson Lake and Lady Slipper Lake. The presence of the Timm Lake Dam reflects localized water management efforts within this prairie environment, where the grid of farm roads and drainage ditches reveals a century of intensive land use and rural development.
