I agree the water is really green, i think its from the crazy weather. From what i have read its from algea growing. I have also read that it can be very bad for the fish since it uses up all the oxygen in the water. It really concerns me because the fishing has been horrible lately and if doesnt clear up we could have a major fish kill. I think we need a few days of really good rain.
I remember it happening one time when i was younger at a lake in wisconsin, it killed almost every crappie in the lake, you could almost walk across the lake on dead fish.
