ROSEVILLE, Minn. — Zebra mussels have moved into another Minnesota lake — McCarrons Lake in Roseville.

The state Department of Natural Resources announced Thursday, Aug. 22, that the fast-spreading invasive species was found near the McCarrons public boat ramp.

The fingernail-sized mollusks grow rapidly in lakes and rivers. They damage boats, water treatment plants and power plants by choking off water intake pipes.

They are usually spread by recreational boats, when the boats are moved from lake to lake.

Minnesota law requires boaters to clean all watercraft of any plant life or invasive species. When transporting boats, drain plugs should be removed to prevent the tiny eggs from being taken to another body of water.
