Lake Powell continues to pose major mussel threat to Colorado
Published September 19, 2018
Boats that have recently been on Lake Powell are posing a serious threat of infesting Colorado lakes and reservoirs with invasive quagga and zebra mussels, Colorado Parks and Wildlife reports.
So far this summer, CPW and other inspectors in Colorado have found a record 43 boats containing mussels, and 32 of those came from Lake Powell which is infested with mussels. The previous record was just 26 boats.
