I did...a 17 acre lake near Edom, Texas, just northwest of Tyler. It was a week or so after that three day cold snap in November, when water temps didn't rise above freezing for that period. Water temps dropped into the 40's for a short time, and tilapia as big as six pounds each perished. We electrofished the lake, retrieved several of the dead tilapia, weighed and measured them, then released them, so my boat wouldn't stink.
Water was extremely clear, and the fish were laying on the bottom, in six to eight feet of water.
