The Texas Department of Parks & Wildlife on Monday announced invasive zebra mussels have been discovered at Lake Lyndon B. Johnson in the Colorado River basin and Lake Pflugerville. Officials say Lake Pflugerville is a water supply reservoir.
Zebra mussels can clog pipes, damage boat motors and affect other aquatic life. Texas law bars the transport of prohibited invasive species, including zebra mussels. Violators face fines of up to $500 for failing to clean, drain and dry their watercraft and gear in such cases.
Zebra mussels were first confirmed in Texas 2009 at Lake Texoma.
TPWD and partners closely monitor "positive" and "suspect" lakes, as well as other lakes we consider high risk for zebra mussel introductions.
Infested Lakes
Seventeen Texas lakes in five river basins can be classified as fully infested with zebra mussels, meaning the water body has an established, reproducing population: Austin, Belton, Bridgeport, Canyon, Dean Gilbert (a 45-acre Community Fishing Lake in Sherman), Eagle Mountain, Georgetown, Lady Bird, Lewisville, Livingston, Lyndon B. Johnson, Pflugerville, Randell (local Denison access only), Ray Roberts, Stillhouse Hollow, Texoma, and Travis.
