The financial impacts of invasive species in the Great Lakes region could be felt for years to come.
A study from the University of Notre Dame and University of Wyoming estimates invasive species will cost Great Lakes states $200 million a year. Dr. Phil Moy with the UW Sea Grant Institute says those numbers may be a little conservative. He says officials in Wisconsin have come up with numbers close to that just for the effects of zebra mussels on water intake pipes.
