Launch at your own risk!
The public is asked to use extreme caution when using the public launch ramps at Lake Powell. The decrease in water levels has reduced the depth of water in these areas, creating shallow water on the ramps with steep drop-offs. More »
May Mussel Update
The National Park Service (NPS) has identified over 150 adult quagga mussels attached to moored vessels and dock structures at the Wahweap and Antelope Point Marinas in Lake Powell over the last month. The individual adult mussels were not close enough together to successfully reproduce. As mussels are found, they are physically removed from the lake.
Mark Anderson, Glen Canyon Ecologist indicated that although there has been an increase in the number of adult mussels detected, there are still no indications of a reproducing population. "It's likely that the mussels were introduced via ballast or bilge water from a boat(s) that was not cleaned, drained, or dried."
Boats, docks, and cables in the Wahweap Bay and Antelope Point areas will continue to be assessed by the NPS and other dive teams.
Superintendent Todd Brindle remains hopeful that these latest results are not evidence of an established population of mussels. "With this early detection, the mussels are being physically removed from the lake, decreasing the potential for them to reproduce," said Brindle.
"Prevention is still the most effective way to fight invasive species, so we will continue the boat inspections that are currently in place," said Anderson. "Everyone needs to continue to clean, drain, and dry their boat and equipment after every use."
Additional monitoring information and updates are posted on the Glen Canyon National Recreation Area webpage at www.nps.gov/glca/.
