ST. PAUL, Minn. (AP) - Zebra mussel larvae have been discovered in Lake Winnibigoshish, one of Minnesota's biggest lakes.
The Department of Natural Resources says two of the microscopic larvae were found in a water sample collected from the state's fourth-largest lake in mid-July. But 14 other sets of samples collected last summer turned up no additional larvae, which are called veligers
The DNR stresses that no adult zebra mussels have been found in the popular fishing lake. But Rich Rezanka, DNR invasive species specialist, says it's prudent to list Winnibigoshish as infested.
He says the presence of veligers suggests a reproducing population of zebra mussels somewhere in the lake.
The DNR says anglers and boaters should be extra vigilant in ensuring their boats and other equipment are clean before leaving a lake access.
