This is a set of the corrected lakes as determined by MPCA's surface water quality assessment program submittedfor the 2022 reporting cycle to US Environmental Protection Agency (EPA). Once declared to be impaired, these lakes have subsequently been removed from the impaired waters list due to one of the following reasons: Flaws were identified in the original listing; Applicable water quality standards (WQS) are attained, due to new assessment method; Applicable WQS attained, original basis for listing was incorrect; Applicable WQS attained, due to change in WQS; Data or information lacking to detemrine water quality status; 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 corrected lakes are a small subset of the NHD and DNR lakes, only that subset is included in the dataset. To be notified of updates to this shapefile, please send an email to kristofor.parson@state.mn.us
These data are intended to be used for planning, informational, and cartographic purposes related to surface water quality in Minnesota.

These data have been audited to ensure every lake included in the proposed 2022 record of corrected waters has a corresponding feature within this spatial dataset. Date of test:11/01/2022
These data contain a feature for every waterbody in the proposed corrected waters dataset. High-resolution NHD is the primary dataset from which these features are drawn. If no feature exists in the NHD, the MN DNR division of waters lakes database is the source.
The processes used to create and maintain high-resolution NHD data can be requested from MPCA. Because NHD data can be downloaded using several user-defined areas, the process descriptions can vary for each download. The NHDMetadata table contains a list of all the process descriptions that apply to a particular download, and those descriptions can be associated with the impaired waters polygons by MPCA staff upon request. MN DNR lake polygons are maintained to meet DNR business requirements, however, MPCA makes requests for DNR to add lakes to thier lakes DB for cases where MCPA monitors a waterbody that does not have an existing DNR feature. For information on specific polygons contact MPCA.

All lakes contained in this shapefile are on the corrections tab of the 2022 Impaired Waters list prepared by the Minnesota Pollution Control Agency.
AUID: Assessment Unit ID, a waterbody identifer based on the MN DNR lake ID. This AUID constitutes a unique identifer for each lake in the dataset.
NAME: Name of the lake associated with the AUID.
BASIN: The name of the basin (HUC4) in which this waterbody is located.
POLLUTANT: Name of the parameter for which the waterbody is delisted.
Values: Nutrients: Nutrient/eutrophication biological indicators
COMMENTS:
The rationale for removing this impairment from the impaired waters list.
STATUS:
Possible values:
DRAFT: Has been posted for public comment.
PROPOSED: Public comment period is closed, has been submitted to EPA.
FINAL: EPA has reviewed and approved the delisting.
