Flooding in Evesham

In contrast to the exceptionally dry winter we had last year, we've had plenty of rain this time. It rained almost everyday for a couple of weeks at the end of February, and then more heavy downpours at the beginning of March brought the worst flooding in Evesham since 1998. The park behind our house became a lake, and the river almost got over the wall into the courtyard of Monks Walk. That danger has now passed after a virtually rainless week, but the forecast is for more rain in the next few weeks. Anybody know how to build an ark?
