2022 Map of Union Lake

About this map

Union Lake and Lake Sarah dominate this Polk County landscape, which is defined by an intricate network of glacial lakes and prairie wetlands. The map reveals a deeply rooted rural community, marked by family-named landmarks and historical burial grounds such as Bailey Cem and Storelvedalen Cem. The transition from natural waterways to managed agriculture is evident in the presence of County Ditch Number One Hundred Thirtythree, which channels water toward the Sand Hill River in the south. The presence of the Hemmingsen Private Airport suggests the continued importance of general aviation in these open northern plains, while the dense concentration of smaller bodies of water like Crooked Lake and Maltrud Lake highlights the region's characteristic post-glacial topography.
