Aquatic invasive species (AIS) personnel from the Utah Department of Natural Resources (DNR) have stopped more than 120 mussel-infested boats this year, most of which had visited Lake Powell, from launching at other Utah waterbodies. So far in 2018, more than 100 mussel-infested boats have been quarantined, a significant increase compared to recent years. "The quagga situation at Lake Powell has worsened. If you boat at Lake Powell it's very likely your boat has quagga mussels on it," said AIS Program Coordinator Nathan Owens. "With more mussels in the lake and lower water levels more boaters have mussels attached to their vessels than in past years. Our techs are regularly finding them on and in boats that have only been in Lake Powell for a day or two — something we haven't experienced in the past." Boaters that visit another lake or reservoir after visiting Lake Powell will have their boat inspected again. If mussels are found the boat will be decontaminated and quarantined, if necessary.

It is crucial to keep the mussels from moving from Lake Powell to other lakes and rivers. Utah and Arizona state laws require you to clean, drain, and dry your boat when leaving Lake Powell using self-decontamination procedures. Additional steps are required if you launch on other waters without a significant drying period or if you are on Lake Powell for more than 5 days.
