Aquatic Invasives Early Detection and Response
Eurasian water milfoil was found in Osprey Lake in 2005. An herbicide treatment using 2,4-D was done in June of 2006. Eight acres of EWM were treated May 22, 2006 with 125 lbs of Navigate herbicide per acre. Surveys done the beginning of July showed only a few occasional scattered EWM plants in the treatment areas. Another survey on July 31, 2006 showed no increase in EWM from prior surveys. On August 2, 2006 a crew from the WI DNR completed a point intercept survey of the lake. They found no milfoil on the southern portion of the lake and only a few scattered plants near the inlet from Round Lake.
