ZEBRA mussels have been found now in Canyon Lake and Lake Travis. We are quite worried about having them hitchhike to the SM River and the Comal where their impacts could be serious. Mussels and their floating, nearly invisible larvae are being dispersed into the lakes and down into the rivers below those lakes. In our area, the larvae are going to be in the Guadalupe River and thus any boats, toys, floats, life jackets or tubes that are used there and then brought to the SM River will carry them. Washing your boat with bleach is supposed to kill them, but so far the spread of these tiny mussels has not been stopped, even by the most stringent of boat cleaning rules.
During the meeting last week, some members of the Habitat Conservation Plan expressed concern about them trying to attach to vegetation like wild rice that would then be weighed down, but we are hoping that research will find that the waving nature of wild rice leaves and our good flowing river will help prevent that attachment. Still water seems to be more conducive to these mussels
Much more research needs to be done, so for now, let’s just focus on washing our gear. Here’s a link to Texas Parks & Wildlife, about cleaning your boats and gear: Preventing Spread of Zebra Mussels
