Permit to Control Eurasian Watermilfoil Issued

The Lake Iroquois Association (LIA) and the Lake Iroquois Recreation District (LIRD) are pleased to announce that an Aquatic Nuisance Control permit for the use of the herbicide, ProcellaCOR, to control the infestation of invasive Eurasian Watermilfoil (EWM) in Lake Iroquois has been issued. After many years of research and planning, we now have tools that promise to allow us to really begin to control the EWM infestation in the lake. The use of herbicide is one part of a multi-pronged effort to reduce and control this invasive and to begin to restore a more natural aquatic plant habitat in our lake. Besides this permit, we have permits to do  Diver-Assisted Suction Harvesting (DASH) and to selectively place bottom barriers. These efforts along with our outstanding greeter and boat wash program, our robust education and outreach efforts to lakeshore property owners and lake users, the completion of several runoff prevention projects, and our work to reduce Beebe Lane erosion all combine to protect and enhance beautiful Lake Iroquois.   

We have begun coordinating dates and creating a timeline for these various activities. Barring any restrictions due to COVID, we expect to do one day of herbicide treatment in late June and several weeks of DASH in August. As things fall into place, we will share more details with you. In the meantime, you can find the full herbicide permit which includes all the conditions which must be met on our website at
