Thanks for additional info! Update: I have collected 22 dead perch as of this afternoon. One of the bigger 9-10" redear floated up as well but looked like it had been dead a while. Saw a couple more perch out there in about the top foot of water swimming slow but none of the fish have been up gulping air. Bunches of minnows = hundreds dead on shore. Not enough to make a dent though as I have a lot of minnows still doing fine (photo of one school). My wife picked up a test kit so I can check levels tonight and report back. I have added new pics from the dead today.
