Exotic and Invasive Species
The Zebra Mussel Threat
A native of Eurasia, the destructive zebra mussel was first observed in North America in 1988 in Lake St. Clair, on the border between Michigan, USA and Ontario, Canada. Since then the zebra mussel has spread to various states located along the Mississippi Waterway and has been reported as far west as Utah and California.
The first Texas infestation was found in Lake Texoma in 2009. As of December 2013, populations have been documented in lakes Belton, Bridgeport, Lewisville, Ray Roberts and Texoma. Boaters and anglers on those lakes and adjacent waters must take special precautions to discourage the spread of this dangerous invader.Zebra mussel DNA has also been documented in several other water bodies but to date no adults or veligers have been found to verify their presence.
