Aquatic Invasives Grant
Aquatic Invasives Control
To address aquatic plant management, a review of current aquatic plant conditions and management techniques is necessary to be sure that the lake is being managed in the best way possible for the resource and its users. To that end, this report outlines past management, the current conditions, and a review of best management actions moving forward.
For more than a decade, the members of the Black Otter Lake District have actively managed the aquatic invasive species Eurasian watermilfoil (Myriophyllum spicatum) (EWM) and curly-leaf pondweed (Potamogeton crispus) (CLP). Both species have dominated the lake at various times over this period. Treatments for exotic species date back to 2003. On May 27, 2014, a survey for exotic species was conducted on Black Otter Lake by Cason & Associates staff. This survey was used to determine the area and location of CLP. It utilized the point-intercept aquatic plant survey map as a guide. Surface observations and rake tows were used to determine the abundance of CLP at each location.
