Unfortunately, Basswood Lake joins the list of area lakes (Burntside, Shagawa, Fall, Vermilion) infested with Spiny Waterfleas. Be aware that lakes, such as Crooked Lake, Iron Lake, and Bottle Lake, are downstream of Basswood and are susceptable to infestation since there is no physical barrier between these lakes and Basswood Lake. We need to be particular diligent to prevent the further spread of Spiny Waterfleas and other AIS to other lakes and particular to the White Iron Chain of Lakes. What can you do? Be informed and follow the recommended steps for prevention. Go to the DNR site http://www.dnr.state.mn.us/invasives/index.html for more information about AIS and prevention.
