I boat and fish on freshwater lakes in New Hampshire and some of these
waters are becoming congested with non-native plants, especially
milfoil. There are some waters that more resemble a meadow than a river
or lake. When milfoil reaches this point the water is lost to both
boating and fishing, although some milfoil seems to provide cover for
fish and improve fishing. Waterfront residents seem convinced that the
source of the milfoil is non-resident boats, and the operators of those
boats claim they always inspect their boat for milfoil before
launching. There doesn't seem to be a consensus on what can, or should,
be done, or who should pay for it.

What's being done in your area? I know that southern areas have fought
this battle for years, but it's relatively new in northern New
England.

Once established does it regrow on its own every year after the winter
freeze? I've never heard of it, but I have not done much freshwater
fishing or boating for many years.

Yes, Eurasian Water Milfoil is quite a problem in Minnesota, where it
still freezes in the winter.
