Lake Buchanan has officially been designated as “infested” with the invasive species known as zebra mussels. Scientists with the Lower Colorado River Authority discovered zebra mussel larvae at three different sites around Lake Buchanan in October. Crews working on a floodgate project at the lake discovered settled zebra mussels shortly after, at the beginning of December. If you have stored your boat in the water at a lake with zebra mussels, it is likely infested with zebra mussels and poses an extremely high risk for moving this invasive species to a new lake, TPWD officials said. A map showing all lakes where zebra mussels have been found in Texas can be found here.
