It was all down to luck, I stopped checking the tide tables some years ago, that I arrived at the end of Ham Street as the water ws lapping up againgst the towpath. I suspect that it had been a little higher just before that and the path may even have been impassible, as it always is with a high tide.
The view looks natural enough but anyone familiar with the area, which is almost everyone in Ham, will realise that the high river has claimed a lot of land and a large concrete structure.
