Where is this Sue?

Reading.

Reading Bridge, just downstream of the cyclist, provides a bottleneck
where all the water has to go under the bridge because it can't get
round it. There's a flow meter with a public display, and a post with
the level of the 1947 flood marked on it. The 1947 flood was about half
a metre deeper than when I took that picture. In 1947 there were
streets flooded, this year not.

The floods seem to be worse in places lower down the Thames, below
Weybridge where some tributaries join in.
