In 1999 , Eurasian water milfoil was discovered in Ice Lake
and McKinney Lake, which drains into Ice Lake through a small
stream. Because Eurasian milfoil was widespread, an aggressive
whole lake fluridone herbicide treatment was conducted. It
is expected that Eurasian milfoil will be reduced below detection
levels for 3-4 years; however, it is unlikely that Eurasian
milfoil can be eliminated from Ice Lake. For more information
on this invasive species go to the Minnesota
DNR.

Eurasian watermilfoil typically has 12 to
21 pairs of leaflets. The native northern watermilfoil,
with which it is often confused, usually has 5 to 9 pairs.
