Zebra mussels have been found in another Texas lake, likely because of careless boaters, officials said.
According to the United States Geological Survey, groups monitoring area lakes recently discovered live juvenile zebra mussels near a dam in Lake Lewisville.
The destructive species has already invaded Lake Ray Roberts and Lake Texoma.
Zebra mussels are harmful because they can clog public water intake pipes, damage boats, take over docks and put an end to recreational activities with their razor-sharp edges. They also compete with native aquatic species for living space.
USGS officials believe the population in Lake Lewisville likely arrived on contaminated boats.
"The spread of the zebra mussels is because of people not cleaning their boats and their trailers when they pull it out from one lake to another," Mark Perlstein, a Lake Lewisville boater, said. "Hopefully they'll be a little more diligent and be able to control it that way."
All boaters in Texas are asked to drain the water from and dry their boats before leaving a lake to prevent further spreading.
"With this somber news, I hope Texas boaters will always remember to "Clean, Drain, Dry" their boats, trailers and gear because all it takes is one instance of not properly cleaning to introduce this highly invasive and unwelcome species to a water body in Texas; and once they are established there is no known way to get rid of them," said Carter Smith with the Texas Parks and Wildlife Department.
