Our decontamination station is OPEN for the season. If you need decontamination, please contact the park office at 435-649-9540 to make an appointment. If you have been to Lake Powell and your boat has ballast tanks, you must be decontaminated regardless of the time the boat has been out of the water. This is due to the major infestation at Powell. Mussels are appearing on boats that are there for less than a week.
