This is a proposed set of the lakes assessed by MPCA's surface water quality assessment process for the 2018 303(d)/305(b) integrated report to EPA. EPA approved the data without requesting any changes in January, 2019. These lakes are a subset and enhancement of the 1:24,000 scale National Hydrography Dataset (NHD). In cases where the NHD does not include lakes that MPCA has assessed, additional lakes from the MN Department of Natural Resources (DNR) Division of Waters lakes database are added. Since the assessed lakes are a small subset of the NHD and DNR 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 lakes that support aquatic recreation and those that had insufficient information to render a support judgment.
