DNR says invasive zebra mussels found in Minneapolis’ Bde Maka Ska
MINNEAPOLIS -- The Minnesota Department of Natural Resources has confirmed the presence of invasive zebra mussels in Bde Maka Ska (formerly Lake Calhoun) in the Minneapolis Chain of Lakes.
The DNR announced Monday that the mussels were found by a Minneapolis Park and Recreation Board watercraft inspector who was checking a sailboat as it was being removed from the lake for the season.
Because the sailboat had been moored in Bde Maka Ska for an extended period and because the mussels were young, the DNR concluded there was in-lake reproduction.
DNR staff conducted a dive search in the lake access and mooring areas but found no additional mussels. The Park and Recreation Board is planning to search further.
In September 2017, the DNR confirmed the presence of zebra mussels in Lake Harriet, immediately south of Bde Maka Ska.
Zebra mussels can compete with native species for food and habitat, cut the feet of swimmers, reduce the performance of boat motors and cause damage to water intake pipes.
