In Northwest Arkansas the lowest temperatures I saw were -8 F (-22 C) but more typical was a low in the teens Fahrenheit when it actually got below freezing. I had a frost-free hydrant in that area so fresh water was easy.
I winter I used black rubber bowls for water. If you could set them in the sun during the day the water would stay thawed well into the teens Fahrenheit (-9 C) due to solar heating. The sun does not shine at night and on some cloudy days so they would freeze. I'd smash them against the ground to knock the ice out and refill them. Since the bowls were rubber they would not break.
When I was a kid growing up in East Tennessee we'd cut a hole in the ice in the farm pond for the horses, cattle, and chickens to drink.
