Manitau just became a private lake for those who live there for the next year due to the fact that hydrilla was found while dredging the lake. I understand the fears of the dnr not wanting this to spread but why not just treat the weed? And how do they think it got there?? I'm worried that if property owners on say wawasee or maxi want to shut the public off of the lakes just start you a hydrilla patch and call the dnr and this will be how they handle it!! And why could you not use the lake in the late fall when most weeds have died off?
