- Description
- The 2024 Integrated Report is a biennial publication on the quality of Michigan's water resources. The Clean Water Act (CWA) requires Michigan to prepare a biennial report on the quality of its water resources as the principal means of conveying water quality protection/monitoring information to the United States Environmental Protection Agency (USEPA) and the United States Congress. The Integrated Report satisfies the listing requirements of Section 303(d) and the reporting requirements of Section 305(b) and 314 of the CWA. The Section 303(d) list includes Michigan water bodies that are not attaining one or more designated use and require the establishment of Total Maximum Daily Loads (TMDLs) to meet and maintain Water Quality Standards. It should be noted that these comprehensive datasets include assessment units throughout the state of Michigan and are not limited to those on the Section 303d list. The 303d status of an assessment unit is indicated in the EPA303dImpairment field, with 0 as not listed and 1 as listed. Further information, including a comprehensive 303(d) list, can be found on EGLE's Integrated Report webpage. Field Name Description AUID Assessment Unit Identification number includes the corresponding HUC12 of the hydrographic feature, followed by a unique numeric identifier. This field is used to identify assessment units and submit water quality information to EPA. It should be used to reference assessments described in EGLE's biannual integrated report and EPA's How's My Waterway information system Waterbody Waterbody name derived from authoritative sources or local knowledge. Description A basic location description of the hydrographic features contained in an AUID, can include county, city, town, approximate area, or location type HowsMyWaterwayLink Link to how's my waterway, an EPA data hub that displays additional information about AUIDs EPAIRCategory Environmental Protection Agency Integrated Report Category for an individual AUID. These categories indicate whether a waterbody is supporting designated uses or not. More information can be found here. PartialBodyContactAttainment This field indicates the attainment status of AUIDs in respect to the Partial Body Contact designated use. This refers to the use of a surface water that may cause the human body to come into direct contact with the water, but normally not to the point of complete submergence, such as wading or boating. Water bodies are evaluated for the Total Body Contact (TBC) and Partial Body Contact (PBC) recreation using E. coli bacteria as an indicator for other harmful pathogens. TotalBodyContactAttainment This field indicates the attainment status of AUIDs in respect to the Total Body Contact designated use. This refers to the use of a surface water for swimming or other recreational activity that causes the human body to come into direct contact with the water to the point of complete submergence. Water bodies are evaluated for the Total Body Contact (TBC) and Partial Body Contact (PBC) recreation using E. coli bacteria as an indicator for other harmful pathogens. ColdWaterFisheryAttainment This field indicates the attainment status of AUIDs in respect to the Cold Water Fishery designated use. This use includes the protection of waters where the dominant species under natural conditions would be temperature intolerant indigenous species. Examples include members of the following families: Salmon, Trout, Cod, Whitefish . WarmWaterFisheryAttainment This field indicates the attainment status of AUIDs in respect to the Warm Water Fishery designated use. This use includes the protection of waters where the dominant species under natural conditions would be temperature tolerant indigenous non- salmonid species. Examples include members of the following families: Pearch, Panfish, Bowfin, Bass, Catfish, Pike . OtherIndigenousAquaticLifeAttai nment This field indicates the attainment status of AUIDs in respect to the Other Indigenous Aquatic Life designated use. This use includes the protection of waters for macroinvertebrate and aquatic plant communities. Macroinvertebrate examples include mayflies, stoneflies, and caddisflies. FishConsumptionAttainment This field indicates the attainment status of AUIDs in respect to the Fish Consumption designated use. This use includes the protection of aquatic communities and human health related to. consumption of fish and shellfish. In other words, this use means that not only can fish and shellfish thrive in a waterbody, but when caught, can also be safely eaten by humans. PublicWaterSupplyAttainment This field indicates the attainment status of AUIDs in respect to the Public Water Supply designated use. This use includes waters that are the source for drinking water supplies and often includes waters for food processing. Waters for drinking water may require treatment prior to distribution in public water systems. EPA303dImpairment This field indicates whether an AUID is listed as impaired, or not supporting a designated use, in the corresponding integrated report. 1 = Impaired, 0 = not Impaired
