Historic Wetland Resources
Like other counties in Southern Minnesota, the vast majority of the pre-settlement wetlands in Blue Earth County were drained for the production of crops and the development of homes, transportation and communities.

The Minnesota Department of Natural Resources Minnesota Wetlands Conservation Plan estimated that only two percent of pre-settlement wetlands in Blue Earth County remained in 1981. A complete inventory of historical wetland resources was never collected. The best sources of information about historic wetland resources in the county is the Original Public Land Survey.
