Decontaminating your boat at North Lake Powell Prevent the spread of quagga mussels and other aquatic invasive species By decontaminating your boat, you help protect Utah’s water bodies against quagga mussels and other aquatic invasive species (AIS). Here’s what to expect if you pull your boat out of Lake Powell-North Lake (Bullfrog and Hall’s Crossing). Cost, complexity and calling ahead Cost — Decontaminations are free of charge for watercrafts without attached quagga mussels, but they may take an extended period of time. Please be patient. If you choose to decontaminate elsewhere, check STDoftheSea.com for locations and call ahead to make a reservation. However, be advised that decontaminations are offered at other water bodies on a limited basis. Watercrafts with attached quagga mussels will be directed to a private company to have a decontamination where a fee will be applied. Note- Mussel encrusted boats leaving Hall’s Crossing will need to have the DWR perform the initial decontamination and, depending on the severity, it may need to be transported to a private company for additional decontamination. All mussel encrusted boats will be charged a fee to decontaminate. Complexity — The Utah Division of Wildlife Resources (DWR) can decontaminate watercraft up to the size of a cabin cruiser for those who do not have attached quagga mussels. All other boats will have to meet a 30-day dry time before launching again in Utah. All boats with attached mussels will require decontamination and must also meet the required dry time after decontamination. If the mussel encrustation is extensive, your boat may be placed in quarantine and directed to a private business in the Bullfrog area, where you will need to pay for the decontamination. Calling ahead — Make a decontamination reservation by calling DWR Biologist John Steffan at: 435-299-9562 or contacting the AIS technicians at Lot D, North Ramp or Hall's Crossing.
