Aquatic Invasive Species in Bay Lake

Invasive species are species not native to Minnesota and cause economic or environmental harm or harm to human health. Minnesota’s natural resources are threatened by several invasive species such as zebra mussels, Eurasian watermilfoil and starry stonewort.

Two important missions of the Bay Lake Improvement Association (BLIA) are preventing the introduction of new aquatic invasive species and controlling those that have already infested Bay Lake. BLIA partners with the Minnesota Department of Natural Resources (DNR), Crow Wing County, Minnesota Aquatic Invasive Species Research Center (MAISRC) at the University of Minnesota, Minnesota Lakes and Rivers Advocates (MLRA), and other lake associations. Through the donations from many-generation Bay Lakers and the longtime Runtilla 5K race, BLIA allocates funds to treat and protect our lake. 

Minnesota DNR controls all aspects of public waters, including treatment of invasive species. While there is no lake wide treatment for zebra mussels, BLIA contracts with an outside firm for the treatment and control of the milfoil. Each spring and fall, chemicals are used to reduce milfoil where it is particularly heavy and in areas with active boat traffic. DNR severely restricts treatable acreage.
