Read A DNR Article: The Science Behind The SuperWeed – Eurasian Water Milfoil

The Okauchee Lake Management District has conducted aquatic plant surveys regularly since 1992. Eurasian Water milfoil has been present in each survey and was found in a survey in 1977. In 2013, milfoil was found in 43% of the sample points. This was down slightly from 56% in 2008. The native milfoil was found in only 5% of the sample points in 2013. Milfoil covers a wide range of areas in Okauchee Lake, from the shallow bays to the deep water. Okauchee Lake also has a native milfoil. Native plants, although sometimes a nuisance as well, have helped control the amount of milfoil. The District’s efforts, relying on herbicides and harvesting, is effectively managing the milfoil in Okauchee Lake. To date, there have been no signs of milfoil herbicide resistance in the lake.

Stop The Spiny Water Flea!

As you may be aware there are several aquatic invasive species to be mindful of when boating. The Spiny Water Flea is one such species! The Spiny Water Flea is a small crustacean that hurts lakes by making the water green in color and degrades fisheries. Always remember to clean your boat when removing it from the lake and empty any live wells aboard to prevent the spread of any aquatic invasive species.
