Invasive Mussel Prevention Requirements on Lake Powell

In response to the continued and growing threat of the introduction of quagga and zebra mussels at Glen Canyon National Recreation Area, effective Nov 1, 2009, self-certification of watercraft will no longer be an option at Wahweap Main and Bullfrog launch ramps and screening for the invasive mussels by trained personnel will be mandatory for all vessels.

The monitoring of boats arriving at Lake Powell will be a collaborative and on-going effort among the partner agencies and restrictions may be modified as the threat of infestation is monitored. Keeping Lake Powell mussel-free is essential to maintaining the economic and ecological vitality of the resource and surrounding communities and region.

Boaters are encouraged to continue to help stop the spread of invasive mussels by making sure their vessels and boating equipment are cleaned, drained, and completely dry before moving to a new body of water, make sure that any boats being moved from infested waters to non-infested waters are properly decontaminated prior to launching. We ask for your assistance in this effort by calling (928) 608-6301 if you see anyone launching outside the designated hours listed above.

You are required to comply with Glen Canyon National Recreation Area's zebra mussel prevention program before you may launch your boat on Lake Powell. To remain in compliance with Glen Canyon NRA's regulations your vessel must be certified mussel free. A mussel free certificate must be displayed visibly in the windshield of your tow vehicle. Recertification is required with each new visit.

Failure to display this certificate could result in a mandatory court appearance, up to 6 months in jail, and a $5000 fine.

The launching of motorized watercraft is not permitted at Stanton Creek Beach effective Nov 1, 2010. At remote launch locations boaters are still allowed to self-certify their vessels are mussel-free. Save time when you get to the park by self certifying that your boats are free of zebra or quagga mussels before you arrive.You may do this process online only if you plan to launch from a remote location.

Quagga mussels, a type of invasive mussel commonly referred to as zebra mussels, have recently been discovered for the first time in the western United States. Mussels were initially discovered on January 6, 2007 in Lake Mead. They have subsequently been discovered in other lakes and waterways of CA, NV, AZ, and CO. In the meantime, the National Park Service's existing quagga and zebra mussel prevention program remains in place. Currently, Lake Powell is believed to be free of quagga and zebra mussels. However, zebra and quagga mussels pose a major threat to Lake Powell if they were to become established. Experts fear that zebra mussels could spread quickly through the Colorado River watershed and potentially establish themselves in other river systems.
