High temperatures are largely to blame because once you see air temps getting into the high 80’s and beyond, it’s a fairly good bet that in some ponds the water temperature will be near or above 78 degrees and that’s kind of a magic number. Higher than this and the water’s ability to hold on to dissolved oxygen will begin to drop and DO is critical to fish health.
