The streams are a subset and enhancement of the 1:24,000 scale National Hydrography Dataset (NHD). MPCA adds additional stream reaches. Since the impaired streams are a small subset of the NHD streams, 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 streams that do not need a TMDL plan. 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.

AUID: Assessment Unit ID, a waterbody identifer that is the eight digit subbasin code and the three digit reach number. This AUID constitutes a unique identifer for each reach in the dataset.

The five categories in CALM are as follows: Category 1: all designated uses are meeting water quality standards Category 2: some uses are meeting water quality standards and there are insufficient data to assess other uses Category 3: there are insufficient data to assess any uses Category 4: at least one use is impaired, but a TMDL is not required Category 5: at least one use is impaired and a TMDL is required. These become the List of impaired waters. A reach can only be placed into one Category. For example, if a reach is impaired for one pollutant but the other uses are being met, and a TMDL is required, that reach would be placed into Category 5. Furthermore, if the reach is impaired for more than one pollutant, the reach must stay in Category 5 until ALL pollutants have EPA-approved TMDL plans. For 'bookkeeping' purposes, these Categories can be sub-divided. Category 4 has the following four sub-categories: 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 influence. To be considered 'insignificant', the elimination of the anthropogenic influence would not lead to the attainment of water quality standards and it would not be included in formal pollution reduction goal-setting activities. A reach-specific water quality standard based on local natural conditions has yet to be determined. Upon determination, the assessment unit will be considered non-impaired for the natural conditions and re-categorized to an appropriate category. 4E: Impaired or threatened but existing data indicates a TMDL is not required because impairment is solely a result of natural sources; a final determination of Category 4D will be made in the next assessment cycle pending confirmation from additional information (i.e. water quality or land use). 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 plan is approved by EPA 5C: Impaired by one pollutant and no TMDL study plan is approved by EPA DELISTED: The parameter(s) have been removed (delisted) from the 303(d) list.
