The rule revisions: 1) require mandatory dry time, in addition to a professional decontamination, for all boats found to have attached mussels; 2) require all drain plugs and other devices that retain water to be removed during transport within the state of Utah from all watercraft coming from a waterbody infested with Dreissena mussels; 3) remove the state of Colorado from the list of infested waterbodies/regions; and 4) add quarantine language allowing UDWR Conservation Officers to restrict watercraft from launching without taking possession of the watercraft.
