About this map

Lake Shetek and Lake Sarah anchor the southern reach of this prairie landscape, where the headwaters of the Des Moines River and Cottonwood River begin their descent across the Minnesota plains. The drainage patterns are defined by numerous glacial depressions, including the notable Great Oasis Lakebed and Bigel Lakebed, which have been historically significant for regional agriculture. A dense network of state wildlife management areas, such as the Prairie Marshes State Wildlife Management Area, reflects a commitment to preserving the original wetland character of the region amidst the agricultural grid.
