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 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.

This MrSID Gen 4 file was derived from the 2017 orthogonal imagery produced from nadir images captured by Pictometry International during the Spring of 2017. Automatic aerial triangulation (AAT) was performed. The triangulated frames were rectified to an Oakland County-provided LiDAR derived DEM. Mosaicing was performed using an automatic seaming algorithm and manually edited to eliminate seams through elevated features where possible.

This data is visualized in the Michigan Orphan Wells Dashboard. Michigan’s Orphan Well Program was created in 1994. Orphan wells are abandoned or improperly plugged wells for which there is no known solvent existing owner or operator. EGLE’s Oil, Gas, and Minerals Division (OGMD) worked with the oil and gas industry for the passage of Act 308, P.A. 1994, which established an Orphan Well Fund within the Michigan Department of Treasury. OGMD utilizes the fund, paid for by revenue created by a severance tax on the oil and gas industry, to plug and remediate orphan well sites. Since the passage of Act 308 nearly 30 years ago, approximately 400 sites have either been plugged or remediated. As of October 1, 2022, Michigan had 447 documented orphan sites as well as additional associated orphaned facilities, piping, and contamination that remained to be addressed.Beginning October 1, 2022, OGMD began utilizing federal grant funds awarded under the Infrastructure Investment and Jobs Act (IIJA), 2021, also known as the Bipartisan Infrastructure Law Section 40601, to provide additional financial assistance for the Orphan Well Program. The IIJA created three types of grants for states to apply for to help address orphan wells and orphan facilities on federal, state, tribal, and private lands.This data also includes state funded orphan well cleanups. The orphan well data is updated nightly. A NULL in a field means that the field does not have any value.EGLE makes every attempt to ensure data accuracy but cannot guarantee the completeness or accuracy of the information contained within this dataset.

Dams in Michigan are regulated by Part 307, Inland Lake Levels, and Part 315, Dam Safety, of The Natural Resources and Environmental Protection Act, 1994 PA 451, as amended. There are 2,500+ dams in the state, most of which are regulated by Part 315. Dams are regulated by Part 315 when they are over 6 feet in height and over 5 acres are impounded during the design flood. Dams are regulated by Part 307 when a circuit court issues an order establishing the level at which the lake is to be maintained. There are also 99 hydroelectric dams in Michigan that are regulated by the Federal Energy Regulatory Commission (FERC) under the Federal Power Act. The Dam Safety Program is responsible for ensuring the safety of Michigan's state regulated dams. These dams, owned by both public and private entities, are located throughout the state. The program focuses on ensuring that dams are properly constructed, inspected and maintained, and that the owners have adequately prepared for potential emergencies.
