Step 1
Prevention
Courtesy Boat Inspection
Trained Courtesy Boat Inspectors (CBIs) staff 10 public boat launches throughout the watershed, from Memorial Day Weekend through Labor Day Weekend. During inspections, CBIs share information with boaters on how to combat the spread of invasive aquatic species.
Step 2
Early Detection
Invasive Aquatic Plant Survey
Detection is imperative for the successful eradication of invasive aquatic plants. Trained surveyors search shallow water areas for signs of invasive plants. Data collected helps plan a management strategy.
Step 3
Removal
Invasive Aquatic Plant Control
Trained staff remove invasive aquatic plants by installing benthic barriers known as “milfoil mats”, and hand pull plants. A diver-assisted suction harvester (DASH) is used for larger infestations. Harvested plants are later incinerated.
