Thanks for the further clarification, emactxag!

I tend to clutter up some threads with tangentially related questions to the original post.

I wanted more info on Snipe's experiment since he is clear up by I-70.

I believe February 2021 was the coldest temperatures in Texas for quite some time. I do NOT recall any reports of large fish kills from our southern members due to that cold air intrusion onto their ponds with warm-adapted fish.

It appears to me (non-expert) that a cold 3" rain event is a much bigger thermal shock to a pond, than a mid-winter cold snap.
