Water has been clearing up with the cooler weather, still no sign of it yet. Late 2012 it was getting thick and growing off the bottom deep so at ice out in 2013 I added a conservative amount of pond dye, secchi disk readings went from 96" to 36". This kept it growing in less than 3 to 4 ft of water all summer which was about the perfect amount of cover. I'll be OK if comes back, I think I can keep it under reasonable control by actively managing the water clarity. The clearer the water becomes, the more of a problem EWM is as it will grow deeper and utilze more nutrients which will prevent an algae bloom. The trick is to steer the nutrient load into an algae bloom early rather than letting EWM get a cool water head start on a bloom.
