The National Park Service (NPS) has developed a response strategy in accordance with the NPS Quagga/Zebra Mussel Infestation Prevention and Response Planning Guide (2007) to help reduce the spread of quagga mussels from Lake Powell to other lakes and rivers. The Glen Canyon National Recreation Area quagga mussel program has shifted from prevention (trying to keep the mussels out) to containment (trying to keep the mussels from spreading to other bodies of water).
As a result, ramp hours will no longer be restricted and green mussel free certificates no longer required. NPS staff will focus on checking for evidence of attached mussels on boats entering and leaving the lake. Rangers on the ramps, at the marinas, and along beaches will educate visitors on how to stop the spread of mussels with Clean, Drain, and Dry techniques.
Utah and Arizona state laws require that boat owners decontaminate their vessels and conveyances to avoid the transport of quagga mussels to uninfested waters.Specific information on state laws for Utah can be found at www.wildlife.utah.gov/mussels or for Arizona at www.azgfd.gov/ais.
"Now that the quagga mussels are in Lake Powell, we need to focus our efforts on containing them," said Superintendent Todd Brindle. "We all put up a good fight for 14 years to keep Lake Powell mussel free, but now we need to work just as hard to protect other lakes and rivers."
