About this map

Oza Tanka Lakebed dominates the central portion of this Faribault County landscape, illustrating the systematic agricultural drainage of the Minnesota prairie. The terrain is defined by a dense network of engineered waterways, including Judicial Ditch Number Six, County Ditch Number Seventy, and County Ditch Number Twentyfive, which channel water toward the E Br Blue Earth River in the south.

For genealogists and local historians, several small burial grounds are scattered across the townships, providing fixed points of reference in an area otherwise dominated by square-mile section roads. These include Saint Marys Cem in the north and the Ellingson Family Cem located near the intersection of modern transport corridors. The map clearly shows how the 19th-century Public Land Survey System grid, marked by designations like t103n r26w, continues to dictate the placement of local routes such as 160th ST and Co RD 108.
