Utah's scenic waterways, fisheries and water delivery systems are being threatened by invasive mussels. Waterways across the country have been invaded and ravaged by tiny, destructive creatures called quagga and zebra mussels. Water enthusiasts need to clean, drain and dry their watercraft to prevent the spread of mussels in Utah's rivers, lakes and reservoirs. For more information visit StopTheMussels.org.
