I like what they do out in the Midwest - like WI and MI and MN. At a
lot of boat launches, they have rinse grates where you can pull your
boat, trailer prior to launch and after launch - the waste water is
contained and any weeds stay there for later recovery. I think that
might be a good program for some of the larger lakes in the NE.

Briefly, i n Wisconsin the Department of Natural Resources (DNR) offer
training to help concerned citizens how to identify a variety of
invasives, including Asian Milfoil. Some grånts also are available to
lake districts to initiate lake inspection programs and volunteers are
recruited to do boat and trailer inspections, especially during periods
of high traffic.

Someone mentioned earlier, I believe, that there are native milfoil
varieties that are beneficial. The problem with the invasive variety is
that it kill all other forms of vegitation and destroys natural
habitat. And it's true that runoff from shoreland and lawns that are
overly developed are equally a threat to habitat. It's interesting that
many people destroy the very features that attracted them to lake
country in the first place.

Good luck. If you want more on Wisconsin's programs you might want to
