I don't know if this is a solution to the problem or if it could even be managed. I do know that in the rivers and streams that flow into lakes Huron and Michigan in the UP, if there is a significant amount of Tannic Acid in them the mussels will not be present. On the lakefront where the river enters the lake you will not find any mussels either. The same goes for the quagga mussels. There is something about the tannic acid that these mussels do not like. I also know if the acid level gets too high the spawning fish will stay out in the lakes until it mellows out a bit.
