Mil-Foiler is a comprehensive, three-step program designed to combat the spread of invasive aquatic plants.


1. Prevention: Courtesy Boat Inspectors

Trained Courtesy Boat Inspectors (CBIs) staff 10 public boat launches throughout the watershed, volunteering weekends and holidays from Memorial Day Weekend through Labor Day Weekend. During inspections, CBIs share information with boaters on the importance of preventing the spread of invasive plants.

2. Detection: Plant Survey

Trained surveyors search shallow water areas for signs of invasive plants. GPS points are used to create electronic maps depicting location, area covered and density of native and/or invasive aquatic plants.

3. Removal: Plant Control

Volunteers are trained in the proper removal of invasive plants by installing benthic barriers known as “milfoil mats” that starve them of light and kill them. Our Diver Assisted Suction Harvester (DASH) team then uses a vacuum hose to remove the dead plants from the water. Harvested plants are later incinerated.
