Minnesota Pollution Control AgencyThese are the lakes assessed by MPCA in 2009 for the 2010 reporting cycling to EPA. The lakes are a subset and enhancement of the 1:24,000 scale National Hydrography Dataset (NHD). MPCA adds additional lakes. Since the assessed lakes are a small subset of the NHD waterbodies, only that subset is included in the dataset.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.Resource publication date.Filesenv-assessed-lakes-2010engPublic2010 Lake Assessments [Minnesota]DatasetsMinnesota2012-03-08Minnesota Geospatial Commons
