Most lakes in Minnesota have zebra mussels they just haven’t been declared yet. Young mussels are microscopic. 0 chance of keeping them out of any lake over time.
Ais action by the dnr is just wasting money. Money that could go to useful things like boat ramps…….
Cities, counties and lake associations have used ais as an excuse to illegally close public launches and or change the allowed time you can use them.
