This is a proposed set of the streams 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 streams are a subset of the 1:24,000 scale National Hydrography Dataset (NHD). This dataset includes streams which have a US EPA approved TMDL plan, those that do not yet have a TMDL plan approved by the US EPA, those that do not need a TMDL plan, and those that had insufficient information to render a support judgment.
