This video from North Yorkshire in England says about itself:

Malham Cove as never seen in living memory

6 December 2015

Unprecedented amounts of rain created this unique phenomenon this morning. Talking to 2 neighbours who are both around 80 and have both lived in Malhamdale all their lives, they have never seen this happen before, and some suggestions are that it could be nearly 200 years since it was last recorded.

The waterfall started again because of rains caused by the storm Desmond. It lasted only for a few hours.
