Download In State Plane Projection Here. This is our working version of the Lake County boundary. Although technically the county's eastern border extends eastward into Lake Michigan to the state line where Illinois meets Michigan, we routinely use the Lake Michigan shoreline as our eastern boundary for mapping purposes. The north, west and south boundaries are based on a compilation of survey data which aligns well, but not perfectly, with the border as mapped by neighboring counties and the State of Wisconsin, which forms the northern boundary of the county. Update Frequency: This dataset is updated on a weekly basis.

The Central Lake County Joint Action Water Agency (JAWA) is a consortium of the municipalities of Grayslake, Gurnee, Lake Bluff, Libertyville, Mundelein, Round Lake, Round Lake Beach, Round Lake Heights, Round Lake Park and Lake County Government representing the communities of Knollwood/Rondout, Vernon Hills and Wildwood for the purpose of supplying Lake Michigan water to these geographic areas.

The lake contours were digitized by a number of different sources, but largely through the GIS group at the Institute for Fisheries Research. Lakes are associated with a New Key, a unique identifier that is a combination of a country code with a unique lake code (Breck, 2004; Humphrys and Green, 1962). Each contour has a maximum and minimum depth. The minimum depth is the value of the contour line and the max value is either the value of the next deepest contour or the deepest point within the contour if there is no next deepest contour.

The United States Environmental Protection Agency (USEPA) requires Michigan to attain the National Ambient Air Quality Standards (NAAQS) for six criteria pollutants. The data contained in this layer file outlines the statewide nonattainment areas and maintenance areas for the 2015 Ozone NAAQS as designated by the USEPA. The nonattainment areas consist of two partial counties (Allegan and Muskegon) and one full county (Berrien) located on the west side along Lake Michigan. In southeast Michigan there is a seven-county Attainment/Maintenance area. Further information about the six criteria pollutant NAAQS and Michigan’s ozone designation status can be found on EGLE Air Quality Division’s SIP and Attainment webpage.

Additionally, areas which were initially designated as nonattainment and have since come back into attainment are classified as Attainment/Maintenance.

The area within two (2) miles of the break walls at Rogers City. Restrictions: Harbor closure shall apply.Created a new point shapefile in ArcGIS 8.1. A point was located on the USGS Presque Isle county 1:24,000 DRG as outlined in the Consent Decree 2000 documentation. The point was generated on the nautical light located at the southeast end of the breakwall. A two mile buffer was then generated from the point shapefile using the buffer wizard tool in Arc Map. This buffered point location was then intersected with the National Oceanic and Atmoshperic Administration - Great Lakes Environmental Research Laboratory (NOAA - GLERL) shoreline layer using the intersecting tool from the geoprocessing wizard in Arc Map to create the final Rogers City Harbor Closure layer. The desired features were then reprojected from Michigan georef to Decimal Degrees to create the final Northern Lake Huron Inter- Tribal Fishing Zone layer. The NOAA - GLERL shoreline layer was cleaned by both Great Lakes Commission (GLC) and Lake Huron GIS (MDNR - LHGIS) after completion.The boundaries represented on consent decree maps are approximations based on the text contained in the 2000 Consent Decree.
