Our Work

Milfoil Control  -  One of our major ongoing maintenance efforts has been to control the invasive species variable milfoil in our lake. Our monitoring, diving, and treatment efforts have resulted in a significant reduction of new plants since 2018. 
Lake Host Program - Protecting our lake from invasive plants and animals is critical.  Large areas of invasive plants in Contoocook Lake would make swimming and boating difficult and possibly dangerous. Invasives are expensive to control and nearly impossible to get rid of.
