Amount of milfoil removed annually from Walsh Lake


In 2005 we discovered milfoil in Walsh Lake, a small lake near the western border of the municipal watershed. Since then divers have been hand-pulling all the milfoil from the lake each year. Our goal is to completely eradicate this invasive weed from Walsh Lake, which is the only known site infested with milfoil in the municipal watershed. Beavers move fragments of the weed around the lake, making eradication more difficult. In 2008 we discovered a new population of milfoil that they had moved to a location close to their lodge. In 2012 we finally had our first year when no milfoil was found. We will continue to monitor the lake to ensure that the infestation is completely eradicated.
