A Guide to Using This Page
Below you can find the Treatment Maps for the lakes, canals and/or connectors on the Huron River Chain of Lakes. On each map, you will find GPS waypoints. These waypoints are reference numbers to help locate specific locations on a map. If you have an area of concern please provide your nearest GPS waypoint number or the location address. This will allow us to more effectively locate the concerned area.
Please reference these maps and the Aquatic Services online calendar below for herbicide treatment areas and the dates of application.
