Invasive quagga and zebra mussels are a major threat to our quality of life. They are small, clam-like creatures that reproduce rapidly and deplete nutrients in the water. They jeopardize power and water infrastructures, damage ecosystems and destroy recreation. Unfortunately, these mussels are not the only aquatic invasive species threatening Utah. View other examples at wildlife.utah.gov/habitat/ans. View a complete list in the Utah Aquatic Invasive Species Management Plan.

In 2008, the Utah State Legislature made it illegal to possess or transport invasive mussels. If you have been in an infested water, you must decontaminate your boat and equipment before entering or traveling with it in Utah.
