Just curious. Was wondering if this is the cause. My pond was built in sept.of 2014. We got the rains and I had wheat and rye grass planted for soil erosion and I still had some dirt wash in the pond. Well the neXT spring summer fish got stocked, and had a spawn several times. My water was nice and green. This year at the end of June my water started to get muddy. I was guessing it's because I have more and bigger fish in there. My pond is somewhere in between half to three quarter acre. Im thinking the bream spawning is causing it. I only have bass and bluegill. Yall have any suggestions. Also water is going down from evaporation. Don't have a well yet.
