Yesterday afternoon I went to my pond and noticed around 100 fish less than 2" dead and floating next to the bank. I went back early this morning to see if I could see any fish gasping for air and I didn't see any. I went back this afternoon and it doesn't appear that anymore have died since I noticed them yesterday. I am leaving to go out of town tomorrow for a week and I am scared that I am going to come home to a pond full of dead fish. What should or can I do.

The pond is 3 acres with the deepest part around 10'. It was stocked with BG, RES and LMB 2 years ago. Up until yesterday all fish seemed fat, healthy and doing well. One thing that worries me is that we are currently building a house around 75 yards from the pond with a lot of contractors coming and going. I hope something that was toxic was not poured into the pond.
