Nothing new about the floods!
From the Brecon County Times 12 November 1931
In Crickhowell the flood, following the severe gale last week, was the highest in living memory. A number of houses in New-road and Bridge-street were seriously flooded and a section of the road, the property of the Llangryney Bridge Company, which connects Gilwern with Llangryney by means of a toll bridge, was washed away.
