Neither is Michigan......The lamprey were out of control back around 1960 and I remember the poisoning of the Boyne River and lake Charlevoix......there hasn't been any further large scale attempt to control them because the predator fish have been taking care of it. I'm sure research is still on going but in terms of controlling a problem, there is none.
As for the zebra mussels in lake St. Clair, nothing was done in terms of federal or state funding that may have had an effect, nature took its course and they have been reduced to sustainable levels and are no longer a problem.
