These beaches are a subset and enhancement of the 1:24,000 scale National Hydrography Dataset (NHD). In cases where the NHD does not include a beach that MPCA has assessed, a custom shape is added. Since the assessed beaches are a small subset of the NHD, only that subset is included in the dataset. This dataset includes assessed beaches which are supporting, non-supporting, and those which have insufficient information to determine support for the Aquatic Recreation designated use.</SPAN></P></DIV></DIV> Assessed Beaches, Minnesota, 2014 (Final) inlandWaters surface water water chemistry water quality <DIV STYLE="text-align:Left;"><DIV><P><SPAN>None</SPAN></P></DIV></DIV> AUID: The Assessment Unit Identifier - a unique code comprised of the 8 digit hydrologic unit code of the reach's HUC 8 watershed followed by a unique three digit numeric string. REACH_NAME: Name of the waterbody associated with the AUID. REACH_DESC: A text description of the beginning and end points of the AUID. USE_CLASS: Use class per MN statute 7050.0470 MILES: Length of the assessed reach in miles OVERALLCAT: The overall category of the lake according to Minnesota's adaptation of the EPA's Consolidation Assessment and Listing Methodology (CALM) categories and subcategories. 1: All designated uses are met and no use threatened. 2: Some uses are met; none are threatened and insufficient data to assess other uses. 3A: No data or information to determine if any designated use is attained. 3B: Data are available for a review and generally indicate non-support, but insufficient data and information to determine TMDL impairment. (Example: single lake data point showing non-support) 3C: Data available that currently has no assessment tools to allow its use in assessing. (Example: data with only eco-region expectation standards) 3D: Data are available for a review and generally indicate full support, but insufficient data and information to assess for category 1 or 2. 3E: Data are available for a review, but insufficient data and information to determine full support or TMDL impairment. (Example: lake data just below the threshold showing non-support) 4A: Impaired or threatened but all needed TMDLs have been completed* 4B: Impaired or threatened but does not require a TMDL because it is expected to attain standards in the near future* 4C: Impaired or threatened but does not require a TMDL because impairment not caused by a pollutant* 4D: Impaired or threatened but does not require a TMDL because impairment is solely a result of natural sources* 5A: Impaired or threatened by multiple pollutants and no TMDL plans approved. 5B: Impaired or threatened by multiple pollutants and either some TMDL plans approved but not all or at least one impairment is the result of natural conditions. 5C: Impaired or threatened by one pollutant. * Assessment units falling into category 4 are impaired waters, but are not part of the 303(d) list because of the reasons given above in the category descriptions. EPA has identified subcategories 4A, 4B, and 4C for classifying a segment, where available data and/or information indicate that at least one designated use is not being supported or is threatened, but a TMDL is not needed. Minnesota has chosen to further subdivide Category 4C into subcategories 4C and 4D to differentiate between cases of impairment due to non-pollutants (4C) and natural background (4D). All category 4 waters appear with the category 5 waters on an impaired waters inventory, which is a comprehensive list of all the current impaired assessment unit/pollutant combinations. CYCLE_LAST: The last cycle during which the waterbody was assessed. WATER_SIZE: The length of the stream, according to the National Hydrography Dataset.
