We all know that water freezes at around 32 degrees. Say that there is a waterfall with a rapid flow of a river, and the air tempurate is 10 degrees for a week, is the water below 32 degrees and not freeze?

Water is properly thought of as turning to a liquid at 32 degrees f. Ice crystals can start to form at around 37 degrees conditionally speaking.
Water falls do freeze over. Water continues to flow behind the ice-face.
As for temp. Water will not fall below 32 degrees without metal-chlorides suspended within. Most all naturally flowing water has these substances suspended in abundance.
The other factor in "freezing point" (properly called 'melting point') is air pressure. At altitudes boiling and melting points shift.
