THE MADISON LAND BRIEF
Land in the
Erie/Ontario Lake Plain setting.
Madison township has 43.4 square miles of land in Lake County. Its Census boundary intersects Erie/Ontario Lake Plain, within Eastern Great Lakes Lowlands.
Glacially shaped lowlands and irregular plains border the Great Lakes and adjacent hills. The lakes influence regional weather, while local landforms reflect both glacial deposits and former shorelines.
Regional context: Eastern Great Lakes Lowlands ↗ · Classification from the Census boundary intersection
The Census reference point falls outside the regional layer’s mapped footprint. This classification uses the actual place-boundary intersection, with Erie/Ontario Lake Plain representing its largest mapped overlap. Shorelines and dataset boundaries can differ.
Erie Drift Plain in Madison
Low rounded hills, glacial moraines, kettles and wetland areas define the Erie Drift Plain. Its terrain is more varied than nearby flatter farming regions and less rugged than the unglaciated plateaus.

Madison by land and water
The Census records 141.3 square miles of water within Madison, or 76.5% of its total area. That share is close to Lake County’s 76.6%. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Madison township has 18.1 times the land area of nearby Geneva-on-the-Lake village (2.39 square miles). These areas describe boundaries, not comparable property prices.
