A great day for watching this happen again will be the 1st March .... which is the highest tide of the year ....(7.78m)
Down the sideroad that you mentioned Peter , there will be loads underwater and in front of the White Cross on Richmond riverside .....
always good for a giggle.....
Expect the lifeboat will be out recusing walkers stranded on high ground off the towpath too , Marble Hill park is a favourite for this ...
last year they rescued a really fat Nanny and the local paper ran the headline 'Large Woman in River Rescue'
