Photo Gallery | Lake Mead Officials Give Lesson in Mussel Removal


Fish and wildlife officials from six other states received a lesson in removing the invasive Quagga mussel Wednesday.

Officials from Lake Mead showed how they use a pressure blaster with water at 108 F to kill the mussels and wash them from boats.

The tiny mussels attach to boat engines and hules, pipes and underwater structures. According to the park service, the mussels cause millions of dollars in damage every year.

Representatives from Utah, Wyoming, Oregon, North Dakota, Montana and California hope to keep the species from invading their waterways.

The mussels first showed up in Lake Mead in 2007, but because Lake Mead is not home to a predator to feed on the mussels their numbers are now estimated to be in the trillions.
