So they have discovered zebra mussels in the lake that is the headwaters for our river. Its also in the other reservoir and in the Cottonwood river as well as the Neosho now. We have good flathead and channel cat fishing, with a few other less desirable. What did zebra mussels do to your fishery when they invaded. I guess there is debate on whether they can even survive in our river because it is so muddy.
