Our board members have done their research and discovered a safe and effective Herbicide alternative to the options above. Herbicide 2,4-D is a selective, root-killing systemic herbicide that controls submersed, immersed, and rooted floating aquatic plants. Using the granular form of the treatment early in the Spring is effective and when timed correctly it will only target Watermilfoil. The granules sink directly into the plant bed, visibly expand over a period of several hours, and suspend a layer of herbicide where the plants are. The herbicide is slowly released in controlled amounts. As the plants begin to grow the herbicide is absorbed through the leaves stems and roots. Growth is halted and the plant dies. Many lakes treated with 2,4-D have had great success in eradicating milfoil with this herbicide.
Treatment is done by specialists approved by the IDNR. Treating the entirety of each lake is not recommended. A mapping of the location of Watermilfoil in both lakes must first be done before deciding where treatment areas will be. Then a representative of the Lake County Health Department must review the maps and decide what is safe for our lakes how many areas in each lake can be treated. It is anticipated that East Loon Lake will receive more treatment than West Loon Lake due to the heavy infestation there. It has always been LLMA’s goal to protect and preserve the pristine quality of our lakes.
Restrictions after applying 2,4-D: Animals and humans should not drink water from the lake for 21 days from time of application. There is no restriction on swimming or fish consumption. Do not water vegetables or ornamental plants from the lake for 21 days from time of application. While no safe method of completely eradicating Eurasian Milfoil has been found, there are ways to arrive at the point where it is no longer intrusive.
Water Run-Off – Environmental Awareness Begins with KnowledgeWhat we can do to help keep our Lakes clean?
Much of the pollution that enters our lakes is caused by water run-off from surrounding watersheds. A watershed is the area of land where all of the water that is under it or drains off of it goes into the same place. When it rains, chemicals, e coli bacteria and other pollutants can be carried along in the excess drainage that finds its way into lake water. Good lake stewardship requires that we become aware of where these pollutants originate and take steps to eliminate them.
Sometimes we need to look no further than our own backyards to find some of the culprits:
- Is your septic system working properly?
- Do you use recommended fertilizers on your lawn and garden?
- Is your shoreline protected against erosion?
- Do you have a buffer strip of un-mowed native vegetation at least 25 feet wide along the shoreline? This can greatly slow nutrient laden runoff from entering a lake.
- Do you routinely keep your yard free of pet and animal waste?
