What is being done
to control Eurasian watermilfoil
in Lake Minnetonka?
The Lake Minnetonka Conservation District, with assistance from Hennepin
Parks, currently manages nuisance growth of Eurasian Watermilfoil in Lake
Minnetonka in cooperation with Department of Natural Resources and lake
homeowner associations. They primarily use mechanical harvesting to manage
nuisance Eurasian Watermilfoil, but also use chemical treatments in small
areas around boat launches and fishing piers where harvesters can't operate.
decides where and when to harvest Eurasian watermilfoil in Lake Minnetonka?
The Lake Minnetonka Conservation District (from their 1999 Harvesting
Report) states that harvesting priorities were based upon impediment
to public boat navigation on the open water, with higher priority
given to areas of the lake that were matted. Although there were some
areas of the lake with significant milfoil growth that was not aesthetically
pleasing, they generally did not harvest them unless they were impeding
public boat navigation.
Particular attention was paid to cleaning shoreline of fragments generated
by the harvest before leaving a bay. Where possible, shoreline clean-up
was done the next day after fragments had a chance to drift to the
shore. Milfoil fragments were collected from residential shorelines
when piles were evident to the crew. This practice has reduced fragment
complaints by the public.
