I have seen my fish at the surface quite a bit here lately and was also conserned. Auburn Indiana area. I saw my triploid carp surface for the first time since I bought them 2 months ago. I also have low amounts of rooted weed and algea. I do live in the woods with hills all around. No wind. My pond is covered with leaves and cottonwood debris, I cannot keep up. My pond is the lowest by far I have seen it since I bought the place. I do run an aerator though, and have a bigger better one on the way. Hope it gets here soon! The answer anyways is no, I have not had dead fish here yet, but while fishing on Adams Lake in noble county we saw tons of dead gills and rockbass 11"+ floating the banks. The Conservation Officer there said that this was the first time he had seen that many dead there. Pray that this rain gets here soon! Good luck
