Invasive, pest species now infesting Lake Travis

I heard this sad news on our local NPR affiliate, KUT 90.5 FM, yesterday.

Texas paddlers should be aware that an invasive pest species, the Zebra mussel (Dreissena polymorpha) has become established in Lake Travis (now classified as ‘infested’).

Our sister club, Hoewa’a Dallas OCC, should be aware that Lake Ray Hubbard is classified as ‘suspect’ as Zebra mussel adults and larvae have been observed in recent years.
All boaters – including canoeists and kayakers – are required to drain all water from their boat and onboard receptacles before leaving or approaching a body of fresh water in order to prevent the transfer of zebra mussels.

Further recommendations for reducing the likelihood that these pests reach Lake Austin, Lake Travis, etc. can be found at Texas Invasives.

Click to see how rapidly the Zebra mussel has spread from the Great Lakes (accidentally introduced via transport shipping in 1986) throughout freshwater waterways.
