Mike Moran mentioned that there was a hidden historic stream running down Bollo Lane, underneath the District Line (see Geoffrey's pictures!!) ...
..then under Chiswick Road (isn't there evidence of wonky buildings there?)
..then underneath where Sainsburys is and where the Empire used to be...
and then the stream passes by Fishers Lane (often flooded)
and along Chiswick Common Road.
So perhaps it's the streams that are overflowing!!
