We currently don't know the impacts, if any, of the zebra mussels in Bull Shoals Lake. The population is still expanding and will likely crash at some point. Then the numbers will stabilize at some level. At that point, their levels will fluctuate over time. We have found zebra mussels all the way to the dam. However, this hasn't stop us from still monitoring the fish populations in the lake. At this point, we are going to have to figure out a way to live with them.
Again, we haven't found a measurable impact of the zebra mussels besides bothering the anglers.
