I have a fairly new pond that I built last fall. It is about 1/3 of an acre and about 12' deep. New spring rains have it full enuff to start spilling into the grass alittle. I put in 8lbs of fat head last fall with about 30 3" walleyes. I then put another 8lbs of fat heads over the winter. I have been noticeing lots of them dead on the bank and seeing lots of them alive in the muddy water. Not sure what is causeing all the dead minnows. Not sure if walleyes are alive or not. The run off that feeds my pond is not feild run off. I have been told that it should have plenty of oxygen in it, being a new pond. Does anyone know why I'm loseing minnows? The minnows are also trying to move into the grass where the water has run over the bank. Thanks for any responces.
