RCWD surveyed the lake for EWM on June 6th and created the 2017 EWM Delineation Map.  The first thing to note, is that it's a bit different from the 2016 EWM Delineation Map and some homeowners have experienced a reduction in EWM.  Also, the water was still quite high on June 6 and EWM may have still been emerging. 

Per RCWD, aquatic plants can change from year to year based on many factors.  In Long Lake, those factors include water clarity, common carp, and management with herbicides.  Water clarity can vary in Long Lake dependent on seasonal rainfall and temperature.  When high rainfall and hot weather generate algae, there is less sunlight for plants, and you'll see less milfoil.  Common carp are excellent "ecosystem engineers" - they change their environment through their behavior.  Their feeding behavior decreases water clarity, and uproots plants.  Long Lake is known to have a very high carp population, especially in the winter, and we have an ongoing plan for carp control.

We are working with LRI regarding treatment options, but in the meantime want feedback from homeowners regarding the delineation map.  If you feel you have an EWM issue that isn't referenced on the map, please add a comment to this news article with your address so we can note it.
