Lake Shannon Weed Control
The first weed treatment is scheduled to take place the last week of May or first week of June. Please see the information in the pdf file below from Aqua-Weed Control, and watch for their yellow signs.
Why are Pesticides Used?
Pesticides (Herbicides/Algaecides) are used to improve and maintain the recreational uses of water; a well maintained lake or pond may increase the value of your property. Aquatic pesticides can also improve the overall aquatic eco-system. A lake or pond that is choked with aquatic weeds can lead to stunted fish populations, stagnant waters, and low oxygen levels. Certain types of algae can be toxic to man, fish and other aquatic life. Pesticidesare used to bring abalance back into aquatic ecosystem. It is important to know that all plants are not weeds. Therefore, no aquatic management plan should attempt to eliminate all plants from the aquatic system. Aqua-Weed Control Inc. recommends each year a program that both reduces nuisance aquatic plants (usually non-native plants) and maintains specific plant species (usually native plants) to provide cover and food for aquatic organisms that depend on plants and algae for their existence. It should also be noted that the Michigan Department of Environmental Quality (MDEQ) regulates the type and amount of aquatic plant species that can be removed from the lake.
The use of aquatic herbicides can result in water use restrictions being placed on waters that have been treaded. These restrictions are listed on the product labels and/or added by the MDEQ as an added safety measure. When an application is done signs are posted along the area that was treated. Please note that none of the products currently approved in Michigan list a swimming restriction on their labels. However, the MDEQ requires a 24 hour no swimming restriction posted when “plant killing” herbicides are applied. The MDEQ does this as an added safety measure and to prevent swimmers from interfering with the products ability to control the target plants.
