Resources and information on utilizing RRD's data exchange and the Inventory of Facilities.
An interactive map displaying contaminated sites throughout Michigan regulated under Parts 213, 201, and 211.
EGLE's interactive calendar is designed to provide timely information on decisions before the Director, proposed settlements of contested cases, administrative rules promulgation, public hearings, meetings and comment deadlines, and environmental conferences, workshops and training programs.
The Michigan Freedom of Information Act (FOIA) provides all persons (except persons incarcerated in correctional facilities) with access to public records of public bodies. Requests to inspect or receive public records from EGLE must be in writing and describe the requested records with enough detail to enable the department to identify and locate the requested records. Some records are exempt from disclosure under the FOIA or another statute and thus will not be provided. A fee may be charged to process your request. Please note that many records are available that do not require a formal FOIA request.

In 2006, the EPA and its state, tribal, federal, and other partners began implementing a series of surveys of the quality of the nation's lakes, rivers and streams, wetlands, and coastal waters (including the Great Lakes). The probability-based surveys are designed to provide nationally consistent and scientifically defensible assessments of our nation's waters and can be used to track changes in condition over time. The National Lakes Assessment Survey was designed to help the EPA provide regional and national estimates of the condition of lakes, as well as statewide assessments for those states who participated in the Survey.
The goal of these Surveys is to address two key questions about the quality of the nation's lakes and reservoirs (not including the Great Lakes):
The Survey used a probability-based sampling design which will provide statistically valid estimates of the condition of all lakes that share similar physical characteristics. The Survey was not designed to provide individual lake assessments to address conditions at particular lakes.
Nationally in 2007, 909 lakes, representing five size classes and distributed evenly across the lower 48 states, were included in the Survey. The lakes were selected randomly and included natural and man-made freshwater lakes, ponds, and reservoirs that were at least 1 meter (3.3 feet) deep and 10 acres in size. Initially, 29 Michigan lakes were randomly chosen as a part of the statistically-based national Survey. EGLE added 21 additional randomly chosen lakes to the survey effort for a total of 50 Michigan lakes to allow for state-based assessment.
The second National Lakes Assessment survey was conducted in 2012. A total of 904 natural and man-made lakes, ponds, and reservoirs that were at least 1 meter (3.3 feet) deep and over 25 acres in size across the lower 48 states were included in the survey. In order to allow for a state-based assessment sampling was conducted at 53 randomly selected Michigan lakes.
The following water quality indicators were sampled at each lake:
Trophic Indicators
Ecological Integrity Indicators
Recreational Indicators
