The Lake Iroquois Fall Plant Survey was just completed and the news could hardly be better. The survey found only one small clump of milfoil in the south cove and none at all anywhere else the lake. Adding to this is the way that native plants have sprung back. We are now seeing native species, such as Elodea canandensis and muskgrass (Chara sp.) as the most common aquatic plant species in the lake. Compare this to the 2019 plant survey, done before the ProcellaCOR treatment, where Eurasian Watermilfoil (EWM) was the most common aquatic plant in the lake. Once the EWM was gone, native plant species quickly filled in restoring a much more natural aquatic habitat. This is very important for the health of the lake. Invasive species, like EWM, do not provide either habitat or food sources for fish, amphibians, and other native wildlife. You might also have noticed the clarity of our water. Without EWM forming dense, rotting mats on the surface of the water, our lake has been cleaner, clearer, and healthier than ever.
