How did quagga mussels get to Lake Mead?
The quagga mussels in Lake Mead are at least 1,000 miles farther west than any other known colony of quagga mussels. The primary method of overland dispersal by zebra and quagga mussels is through human-related activities. Given their ability to attach to hard surfaces and survive out of water, many infestations have occurred by adults hitching rides on watercraft. The microscopic larvae also can be transported in bilges, ballast water, live wells, or any other equipment that holds water.
