The National Park Service found over a dozen quagga mussels attached to vessels and dock structures in the Wahweap Marina in Lake Powell within the last week.
NPS removed all of the mussels they found and confirm that none of the mussels were close enough to mate for reproduction.
A local marine business was the first to report four small shells on a boat that had been pulled for maintenance to the NPS.
A NPS dive team will be monitoring boats, docks and cables at the Wahweap Bay to make sure there are no further mussels in the waters.
Dive teams had inspected the Antelope Point area beginning in December of 2012 where no mussels had been discovered.
Boat inspections and decontamination stations have also kept quagga mussels from establishing themselves at Glen Canyon National Recreation Area on the Arizona-Utah border.
The mussels have multiplied quickly in other waterways across the West, clogging pipes and water intakes, and depleting food sources used by aquatic creatures.
NPS is asking everyone to take this as a warning. Boaters and visitors need to continue to clean, drain and dry their boats and equipment after every use.
