MLA continues fight to stop Eurasian milfoil
The Minnewaska Lake Association (MLA) continued its five-year plan last week by again chemically treating Eurasian milfiol in Lake Minnewaska in an effort stop the growth of the aquatic invasive species (AIS).
For the second year, MLA contracted with Lake Restoration, a Rogers, Minn. company, to treat milfoil identified in different pockets around the lake. This year, the MLA contracted to treat all 33 acres where the invasive species has been located. Lake Minnewaska is the 13th largest lake in Minnesota at 7,110 acres. Again this year, MLA was permitted to do the chemical treatments by the Minnesota Department of Natural Resources. Last year, the first year the MLA contracted to treat milfoil in Minnwaska, about 15 identified acres were treated.
“The treatment did cut it down in those areas so we wanted to treat all 33 acres this year,” said MLA President Mike Stai. The lake association hopes to treat the milfoil every year for the next three to five years, “if we can continue to get the funding to do so.”
It costs the MLA about $400 per acre to treat the milfoil with DMA-4 herbicide, a checmical that kills roots and all of the invasive species. The chemical is a selective chemical that “leaves most of the native plants unharmed,” according to Steve Symalla of Lake Restoration. He said his company treats Eurasian milfoil in many of the state’s lakes and says the treatment has been effective.
Stopping the spread of milfoil in the lake has become a priority for the MLA, and the MLA board continues to seek donations and state grants that will allow them to continue to kill the milfoil in the lake.
Anyone who wants to donate specifically to the milfoil treatment or to the MLA can contact Mike Stai or any MLA board member.
