NEW BRIGHTON, Minn. — The Minnesota Department of Natural Resources says an invasive zebra mussel has been discovered in New Brighton’s Long Lake.

The DNR announced Thursday, Sept. 19, that the mussel was found by a diver contracted to conduct an early detection survey of the 175-acre lake northwest of Interstates 694 and 35W in the Twin Cities.

The DNR and Ramsey County conducted a follow-up search but didn’t find additional mussels. But the agency said the search was conducted on an overcast day amid murky water conditions, so additional surveillance will be required to determine if there is an established population in the lake.

Meanwhile, the DNR said adult and juvenile zebra mussels have been confirmed in Eagle Lake in Otter Tail County in west-central Minnesota.

The DNR said lake property owners should check boats and trailers, docks and lifts, and all other water-related equipment for invasive species when removing equipment for seasonal storage and report suspected new invasive species to the agency.

Zebra mussels can compete with native species for food and habitat, cut the feet of swimmers, reduce the performance of boat motors and damage water intake pipes.
