New interactive web map shows sites where EGLE has completed Aquatic Nuisance Control plant surveys
February 01, 2023
To better assist the public with accessing this information, Water Resources Division staffers of the Michigan Department of Environment, Great Lakes, and Energy (EGLE) have created an interactive web map showing the distribution of sites where plant surveys part of the Aquatic Nuisance Control (ANC) program have been completed by the program over the years. The map will allow stakeholders to discover which lakes have had AVAS surveys conducted and in what years those surveys occurred, as well as assist them with accessing the survey records via MiEnviro Portal.
The Michigan Department of Environment, Great Lakes, and Energy’s Water Resource Division (WRD) has recorded numerous aquatic plant community surveys as part of the activities of the Division’s ANC program. The ANC program approves permits for herbicide applications to control aquatic plants and algae in waters of the State and through monitoring efforts associated with those permits has conducted surveys in waterbodies across the State of Michigan. These surveys were conducted according to the WRD established Aquatic Vegetation Assessment Sites (AVAS) technique.
The interactive web map can be found on EGLE’s centralized Maps and Open Data Portal as well as the webpage for the ANC. The data can also be viewed in a table format or downloaded by visiting EGLE's Maps and Open Data Portal.
