More than 600 bodies of water in the U.S. are infested with quagga and/or zebra mussels. They cause millions of dollars of damage to boat and water systems by clogging pipes and engines. They also impact the native ecosystem and sport fisheries. Quagga mussels were discovered at Lake Mead in 2007, but so far the introduction of zebra mussels has been prevented. Over the past decade, the park has taken aggressive measures to mitigate their spread.
Your Actions Matter
Before you enter and after you leave the waters of Lake Mead and Lake Mohave, CLEAN. DRAIN. DRY.
Mud, plants and animals that may be lurking on your watercraft, trailer, equipment or on your vehicle will cause the spread of invasive mussels. YOU can stop the spread of aquatic invasive species. Help keep quagga mussels out of other lakes and keep new invasives from entering Lake Mead and Lake Mohave. Clean Drain Dry anything that comes in contact with water (boats, trailers, vehicles, equipment, clothing, dogs, etc.).
Remove all plants, animals, and mud from your boat, anchor, boots and other equipment before you enter and after you leave the water. If traveling to another body of water, rinse equipment and boat hulls with high-pressure, hot water at one of the park's hot water wash stations (see below).
Before leaving the park, drain all the water from your boat, including the motor, bilge, livewell, ballast, hull and anything else that traps water. Leave drain plugs out during transport.
Dry all compartments and equipment completely before entering another body of water.
