Temps...no, EWEST, I should have checked that, my mistake...but I'm (pretty) sure it wasn't turnover. The pond is only 6 feet deep so there wouldn't be stratification, I wouldn't think. Also, aeration is present.
No major rain event during the time this happened. The Texas drought was in full swing.
Cows, that's a possibility. Maybe a mass swiming party by the cows. It's possible I guess they could have been avoiding some kind of insect attack.
I'm really reaching...actually have no idea what happened and probably will never know. Water in all other ponds, two of which are within sight of this one, is perfectly normal. This pond was renovated last fall and since then has had a consistent low visibility due to turbidity, with visibilities of about 10 to 12 inches and steadily improving.
To add to the confusion, we received 2.25 inches of rain this week and the pond actually improved in visibility...so unlike DD's case, I don't believe rain was a factor. Like Theo said, its a mystery.
The good news is that the fish do not seem to be adversely affected, other than not eating much and not growing much during this period. I was worried about the HSB as much as the TGGs but catching a couple of them showed they are doing just fine, also. Strange set of events.
