Zebra mussels – an invasive species that poses serious ecological and economic threats to Minnesota’s lakes and streams – have now spread to Lake Minnetonka, the Department of Natural Resources announced on July 28.
For years, the DNR has worked with lake residents and users to prevent the introduction of zebra mussels to Lake Minnetonka.
Heavy infestations of zebra mussels can kill native mussels, impact fish populations, interfere with recreation, and increase costs for industry, including power and water supply facilities. Native to Eastern Europe and Western Russia, zebra mussels were first discovered in Minnesota in 1989 in the Duluth harbor.
