PHOENIX — A sea creature the size of a fingernail but en masse can potentially take down a boat has been found in three popular Arizona lakes.
Wildlife officials said this week that invasive quagga mussels were present in Canyon, Saguaro and Apache lakes in the Tonto National Forest.
The Arizona Game and Fish Department said the evidence was conclusive.
There was no infestation but the lakes were listed as being waters affected by the aquatic-invasive species. Quagga mussels can damage boat motors and clog water intakes pipes and screens.
They also reduce pumping capabilities at power and water-treatment facilities.
Boaters and anyone else enjoying motorized water recreation activities in the three lakes have to clean, drain and dry watercraft and other equipment.
It’s also state law.
