I did some research on this -- as you probably have too. There is lots of information about the plant itself, how and where it has spread but less information about controlling it. Physical removal seems to be expensive and only partially effective. It is hard to get all roots and shoots and remnants of plants can grow back. I was looking for a government authority that might align closely with the approach of your local forest ranger.  I found information from Minnesota DNR regarding mitigating the spread of Eurasian Milfoil and using our natively occurring milfoil weevil as a biological control in already infected areas. https://www.pca.state.mn.us/eurasian-water-milfoil

A quick list of possible next steps:

1. Call Minnesota DNR to get more details about success, cost, down sides and practicality of using milfoil weevils to eat it. 

2. Contact NFH cabin tracts in lakes known to be infected asking if they have had any support from their local forest rangers in controlling it. This webpage has a list of infected lakes by state. https://nas.er.usgs.gov/queries/FactSheet.aspx?speciesID=237

3. Consider public education and awareness strategies that can help avoid the spread of Eurasian Milfoil to additional lakes.  

4. Lake Tahoe has been threatened by it and may have some. A phone call, would answer if The League to Save Lake Tahoe has a method of addressing it. I know all boats are inspected before they can be launched in Tahoe. 

Butch, I am passionate about removal of invasive species. I would be happy to talk to you about this further and to contribute my time and effort to the ideas I mentioned above or other thoughts you might have.
