I graduated high school in 1981 and in February of that year me and 20 of my friends swam across a spot on the Tennessee river at Kentucky lake, about 100 feet across. It was lightly snowing. The count has dwindled but at least 5 or so have done it every year in February. It is very brisk getting in and when you get out but once acclimated, not horrible. A fun challenge.It's not much swimming - maybe 30-40 feet, usually. The challenge is the cold water (mountain lake in April).
