Some of which include boating and navigational safety regulations, dock and boat storage, licensing and permitting of multiple Lake needs, as well as the management and prevention of AIS (working closely with the MCWD, MN DNR, and other local partnerships and agencies). The LMCD also has the authority to issue high water declarations and associated no-wake restrictions.

2021 04-06 – Community Update on Zebra Mussel Control Research at Lake Minnetonka

Scientists from the Minnesota Aquatic Invasive Species Research Center and the US Geological Survey have been studying how low dose applications of copper sulfate can be used to suppress zebra mussels to limit the impact they have on lake ecosystems since 2016. After several seasons of scaling up and refining the methods through in-water trials at Lake Minnetonka, researchers have been able to optimize the concentration and exposure time to get long-lasting suppression of veligers, juvenile, and even adult mussels with minimal impacts to native species. In 2019, a whole bay treatment was conducted at St. Alban’s Bay.
