On Saturday, January 20, NPS divers found live zebra-type mussels known as quagga mussels (Dreissena spp.) at the Katherine Landing Marina on docks and hulls of houseboats. The samples collected were positively identified by a U.S. Fish and Wildlife Service scientist on Sunday, January 21. Katherine Landing is a developed area on the Arizona side of Lake Mohave just north of Davis Dam in Lake Mead National Recreation Area. The scientist also inspected samples of suspected zebra-type mussels collected from a depth of about 110-feet of water at the Kingman Wash area of Lake Mead and confirmed them to be quagga mussels.For up-to-the-minute reports on invasive mussel sightings please go to www.100thMeridian.org.
On January 18, 2007, NPS divers dove Overton Beach and Echo Bay marinas on the Nevada side of Lake Mead and did not find adult mussels in the developed area.
On January 16, 2007, concession employees at Callville Bay Marina found suspected invasive mussels on four houseboats that had been taken out of the water for routine maintenance and these were confirmed by scientists to be quagga mussels. Callville Bay is on the Nevada side of Lake Mead.
All samples collected to date have been identified as the quagga species of mussels commonly referred to as zebra mussels. See attached pdf map.
The week of January 8, divers from the NPS, Arizona Game and Fish Department, and U.S. Fish and Wildlife Service inspected and found no evidence of adult invasive mussels, at the following locations:
The National Park Service, Bureau of Reclamation, U.S. Fish and Wildlife Service, Nevada Department of Wildlife, Arizona Game and Fish Department, the Southern Nevada Water Authority, and the California Department of Fish and Game are continuing to work together and share resources and expertise to assess the immediate level of infestation, develop an action plan to stop the spread to other waterways, and long-term planning and monitoring strategies.
"Our immediate concern is to ensure we are doing everything we can to stop the spread of invasive mussels from infested waters along the Colorado River to other bodies of water. Many boaters enjoy recreating on all the reservoirs in the Lower Colorado River System. We need to educate our visitors on the important role they have in stopping the spread to other bodies of water," said Lake Mead National Recreation Area Superintendent Bill Dickinson.
