2022 Map of Oza Tanka Lakebed

About this map

The Oza Tanka Lakebed dominates the central portion of this Southern Minnesota landscape, reflecting a region defined by extensive agricultural drainage projects. The area's history of water management is clearly visible through an intricate network of waterways including Judicial Ditch Number Six, County Ditch Number Five, and County Ditch Number Twentyfive. These engineered channels feed into the larger E Br Blue Earth River, which meanders through the southern portion of the quadrangle. Scattered across the rural grid are several small burial grounds that anchor the local genealogy of the area, most notably the Ellingson Family Cem, along with Saint Marys Cem, King Cem, and Dell Cem. The map illustrates a strictly partitioned prairie landscape where the Jeffersonian grid of section lines is heavily utilized for local transport, with routes like Co RD 16 and Co RD 109 serving as primary connectors for the surrounding farmsteads.
