Description: This is a draft set of the wetlands assessed by MPCA's surface water quality assessment process in 2012 and 2013 for the 2014 303(d)/305(b) integrated report to EPA. Waterbodies assessed prior to 2012 may also be included in this dataset unless they have been delisted. The waterbodies included in the dataset will be reported to EPA in April, 2014. EPA evaluates the data and either approves it as-is or modifies it, which may result in changes to this spatial data. These wetlands are a subset and enhancement of the 1:24,000 scale National Hydrography Dataset (NHD). In cases where the NHD does not include wetlands that MPCA has assessed, additional features from the MN Department of Natural Resources (DNR) Division of Waters lakes database are added. Since the assessed waters are a small subset of the NHD and DNR features, only that subset is included in the dataset.
Description: This is a draft set of the lakes assessed by MPCA's surface water quality assessment process in 2012 and 2013 for the 2014 303(d)/305(b) integrated report to EPA. Waterbodies assessed prior to 2012 may also be included in this dataset unless they have been delisted. The waterbodies included in the dataset will be reported to EPA in April, 2014. EPA evaluates the data and either approves it as-is or modifies it, which may result in changes to this spatial data. 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 impaired 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, those that have a US EPA approved TMDL plan as well as those lakes that do not need a TMDL plan.
Description: This is a set of the impaired streams as determined by MPCA's surface water quality assessment process proposed for the 2018 reporting cycle to US Environmental Protection Agency (EPA). Streams declared impaired prior to 2018 are also included in this dataset unless they have been delisted. EPA evaluates the list and either approves it as-is or modifies it, which may result in changes to this spatial data. Note that for the purpose of submitting the impaired waters list to EPA, waterbodies partially or wholly within Indian reservation boundaries are published in separate datasets. The MPCA still considers these waters impaired and has an interest in restoring them. The MPCA respectfully requests that the waters partially or wholly within Indian reservations be symbolized differently on map products so that viewers can differentiate them from waters not intersecting Indian reservations. These streams are a subset and enhancement of the 1:24,000 scale National Hydrography Dataset (NHD). In cases where the NHD does not include a stream reach that MPCA has assessed, a feature is added by MPCA. Since the impaired streams are a small subset of the NHD, only that subset is included in the dataset. This dataset includes impaired streams which have not yet had a TMDL plan approved by the US EPA, those that have a US EPA approved TMDL plan as well as those waters that do not need a TMDL plan. Please keep in mind that the data herein are are subject to change. We ask that any maps made with this data indicate the 'proposed' status.

Description: This theme shows state designated trout streams and tributaries as per Minnesota Rules (6264.0050). Coding has been completed statewide; however, there may be periodic designation changes made during the annual rule revision process. The authoritative source of designated trout streams and tributaries remains Minnesota Rules Chapter 6264 (not this GIS layer). Refer to: http://www.revisor.leg.state.mn.us/arule/6264/0050.html for the official listing of designated trout waters (lakes and streams). Users of trout stream information should be aware that the trout_flag code does not fully describe the extent of protected watercourses with regard to trout habitat and associated state restrictions.
