Minnesota Pollution Control AgencyThis is a set of the impaired wetlands as determined by MPCA in 2009 for the 2010 reporting cycling to US EPA. The lakes are a subset and enhancement of the 1:24,000 scale National Hydrography Dataset (NHD). MPCA adds additional lakes. Since the impaired lakes are a small subset of the NHD lakes, only that subset is included in the dataset. This dataset includes impaired lakes which have not yet had a TMDL plan approved by the US EPA, as well as those lakes that have a US EPA approved TMDL plan.The data set was created as part of the Minnesota Pollution Control Agency's Environmental Data Access System, which allows for public access to surface water monitoring data.March 23, 2012Filesenv-impaired-wetlands-2010engPublicImpaired Wetlands 2010 [Minnesota]DatasetsMinnesota2012-03-23Minnesota Geospatial Commons
