The quagga infestation at San Vicente is common knowledge. I have lost enough fish to shredded lines to prove it. But I wasn't able to find any reference to zebra mussels being in our local lakes. I brought up a limb on Monday of this week, and like most everything at San Vicente it was covered with mussels. Looking at it later, it appears that some of them look a lot like the pictures we see of zebra mussels. Could it be?
