Invasive zebra mussel larva found in lake that supplies Winnipeg drinking water

A larval-stage zebra mussel has been found in water from Ontario's Shoal Lake, which is connected to Lake of the Woods and is the source of Winnipeg's drinking water. A single intact veliger, the microscopic larva of a zebra mussel, was found in one of six water samples taken from the lake, according to a news release issued jointly on Monday by the provinces of Manitoba and Ontario.
