Down the Ock Valley Walk there is still evidence of flood damage over 4 years after the 2007 floods. Dead trees like the curly branched variety in the picture have been left as a reminder.
A planning application has recently been put in on land near St Amand Drive, close to the River Ock, with an attached flood risk assessment by a firm based in Burgess Hill, West Sussex and I quote “… Running near the northern boundary of the site is the (bifurcated) River Ock, which flows east to the Thames (known locally as the Isis.) …”
At that point I started to doubt the flood risk. I have never called the Thames the Isis even when I lived in Oxford. Perhaps there are some in Abingdon that do.
