Lots of good discussion and learning possibilities in this thread.
Scott, was there a sudden cold snap that lasted a few days to week around the event of BG dying? I don't think that would influence water temperature too much but I could mistaken especially if ice was allowed to form.
here in alabama we rarely see ice form on a pond. cold snaps for us are upper 20's for a night time low for a few days and then back to 40 and 50 degree nights. we do go through spells for a week or so where we will have frost every morning. it was 80 here today.
