These are the lakes assessed by MPCA in 2011 for the 2012 303(d)/305(b) integrated report 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 lakes, 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.

All lakes contained in this shapefile are included in the 2012 surface water quality assessments prepared by the Minnesota Pollution Control Agency.
AUID: Assessment Unit ID, the DNR DOWLKNUM with hypens between 2 digit county, 4 digit lake number and 2 digit bay id.
WATER_NAME: Name of the waterbody associated with the AUID. LOCATION: A description of the waterbody's location.
TROPHIC_ST: The trophic status of the lake.
E: eutrophic
M: mesotrophic
U: unknown
O: oligotrophic
H: hypereutrophic
OVERALLCAT: The overall category of the lake according to the EPA's Consolidation Assessment and Listing Methodology (CALM).
1: all designated uses are meeting water quality standards
2: some uses are meeting water quality standards and there are insufficient data to assess other uses.
3: there are insufficient data to assess any uses.
4: at least one use is impaired, but a TMDL is not, or no longer, required.
5: at least one use is impaired and a TMDL is required.
For bookkeeping purposes, thes categories can be sub-divided. Category 4 has the following four subcategories:
4A: Impaired, but a TMDL study has been approved by EPA
4B: Impaired, but a TMDL study is not required because water quality standards are expected to be met in the near future.
4C: Impaired, but a TMDL study is not required because the impairment is not caused by a pollutant.
4D: An assessment unit is impaired or threatened but doesn't require a TMDL because the impairment is due to natural conditions with only insignificant anthropogenic influences. A reach-specific water quality standard based on local natural conditions has yet to be determined. Upon determination of a reach-specific water quality standard, the assessment unit will be considered non-impaired for the natural conditions and re-categorized to an appropriate category.
Category 5 has the following three sub-categories:
5A: Impaired by multiple pollutants and no TMDL study plans are approved by EPA.
5B: Impaired by multiple pollutants and at least one TMDL study plas is approved by EPA.
5C: Impaired by one pollutant and no TMDL study plan is approved by EPA.
CYCLE_LAST: The last cycle during which the waterbody was assessed.
WATER_SIZE: The area of the waterbody, in acres, according to the National Hydrography Dataset.
AQR: Aquatic Recreation Assessment
FS: Fully Supporting aquatic recreation use
IF: Insufficient Information for an assessment
NA: Not Assessed
NS: Not Supporting aquatic recreation use
AQR_CAT: The CALM category for the Aquatic Recreation use class.
AQC: Aquatic Consumption Assessment
IF: Insufficient Information for an assessment
NA: Not Assessed
NS: Not Supporting aquatic consumption use
AQC_CAT: The CALM category for the Aquatic Consumption use class.
AQL: Aquatic Life Assessment
FS: Fully Supporting aquatic life use
IF: Insufficient Information for an assessment
NA: Not Assessed
NS: Not Supporting aquatic life use
AQL_CAT: The CALM category for the Aquatic Life use class.
