If you see a helicopter off the shoreline and are wondering why they are flying there, this is why...........
The Saginaw Bay Cooperative Invasive Species Management Area (CISMA) will be implementing a chemical application for the treatment of invasive Phragmites along parts of the shoreline. Fall is the best time to spray the Phragmites as this is the time of year when they store nutrients in their root system for the winter.
This treatment will take place starting on October 11th, weather permitting. Aerial treatment will be provided by Hamilton Helicopters at a distance of greater than 100 ft from the shoreline. Clarke Aquatics will be providing on-the-ground treatment from the tree line to 100 ft from the shoreline. This buffer will limit the risk of off-target spray from aerial application and provide a more efficient coverage of Phragmites infestations. It is best to stay indoors during the spraying just to be safe. Also, where this treatment has taken place, do not enter the water within four (4) hours of spraying.
This only affects those properties that have signed the Landowner Permission slip. All others will be left unsprayed.
As treatment dates may be subject to change due to inclement weather, please visit for updates and information:
