According to a recent release from the United States Geological Survey (USGS), zebra mussels have found their way to Lewisville Lake.
This coming less than a year following the discovery that the destructive invasive species has been confirmed in Lake Ray Roberts. This is the third lake in Texas, and the second within the Trinity River basin, where zebra mussels have been discovered.
Christopher Churchill, a biologist with the USGS who has been monitoring for zebra mussels in North Texas rivers and reservoirs, discovered the live juvenile on a settlement sampler near the dam of Lewisville Lake.
“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,” Smith said.
Zebra mussels can have economic and recreational impacts in Texas reservoirs. They can clog public-water intake pipes, harm boats and motors left in infested waters by covering boat hulls and clogging water-cooling systems, annoy boat-dock owners by completely covering anything left under water and can make water recreation hazardous because of their razor-sharp edges.
Anyone wishing to receive a supply of informational brochures, wallet cards or posters about zebra mussels to distribute to boaters around lakes Lewisville, Ray Roberts or Texoma, please contact firstname.lastname@example.org.
