More than two dozen divers are scheduled to search parts of Lake Powell in Glen Canyon National Recreation Area for non-native quagga mussels later this month.
The divers plan to enter the water the week of June 10 at Wahweap and Antelope Point marinas to assess the extent of quagga mussels in the lake and to remove all existing mussels.
Earlier this year 14 adult mussels were found in boats and on docks in the reservoir.
Divers and staff from the National Park Service, Aramark, Antelope Point Marinas, and other local, state, and federal agencies will inspect moored boats, docks, cables, and the buoy field in the marina areas during the intensive four-day effort. The location, size, and quantity of the mussels removed will be recorded to help scientists determine the origin and scope of the problem.
“We’re going to give it our best shot to remove all mussels and return the lake to a mussel-free state,” said Glen Canyon Superintendent Todd Brindle. “There is still no evidence of a reproducing colony. This proactive approach and intensive inspection hopefully will eliminate the ability of quagga mussels to spread throughout the lake.”
Park staff encourages the public to maintain a safe distance while the divers are working and to be extra cautious when operating boats in the marina areas during this time.
Current mussel-free certification requirements and boat inspections will continue. The most effective way to fight the spread of invasive species is to clean, drain, and dry your boat and equipment before and after every use.
