This dataset at 1:24,000 scale is a greatly expanded version of the hydrologic units created in the mid-1970's by the U.S. Geological Survey under the sponsorship of the Water Resources Council. The WBD is a complete set of hydrologic units from new watershed and subwatersheds less than 10,000 acres to entire river systems draining large hydrologic unit regions, all attributed by a standard nomenclature. Development of the Watershed Boundary Dataset started in the early 1990's and has progressed to the format and attribution that is now being distributed. The delineation and attribution was done on a state basis using a variety of methods and source data. Each state HU dataset has gone through an extensive quality review process to ensure accuracy and compliance to the Federal Standard for Delineation of Hydrologic Unit Boundaries before and during submittal to USDA-NRCS National Geospatial Management Center (NGMC).

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.

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.

OtherIndigenousAquaticLifeAttainment

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.

This layer outlines the 10 "economic prosperity regions" in Governor Snyder's Region Prosperity Initiative. The Regional Prosperity Initiative is comprised of two parts, an effort by the State of Michigan to align around a common set of service delivery boundaries to create a better structure for collaboration and a local voluntary grant initiative. This geographic delineation is based on county boundaries at the lowest level. Please see the MDOT Metadata Form for additional information. Update Cycle: Michigan RPI Boundaries are static boundaries.Coverage: This is the official boundary delineation for Governor Snyder’s Region Prosperity Initiative (RPI).

Census Designated Places (CDPs) from the Michigan Geographic Framework (MGF) base map. These are the statistical counterparts of incorporated places, and are delineated to provide data for settled concentrations of population that are identifiable by name but are not legally incorporated under the laws of the state in which they are located. The boundaries usually are defined in cooperation with local or tribal officials and generally updated prior to each decennial census. These boundaries, which usually coincide with visible features or the boundary of an adjacent incorporated place or another legal entity boundary, have no legal status, nor do these places have officials elected to serve traditional municipal functions. CDP boundaries may change from one decennial census to the next with changes in the settlement pattern; a CDP with the same name as in an earlier census does not necessarily have the same boundary. CDPs must be contained within a single state and may not extend into an incorporated place. There are no population size requirements for CDPs.More Metadata
