You can build river walls beside it.
Along the bank beside the Ascot Race Course, a new river wall is being built.
Adding to the many kilometres of river walls already beside the Swan.
Yet when I went to take some photos of the original river all, now more than a hundred metres back from the current river position, all remnants had been built over! Back in the 1980’s, as a part of my genealogical research, I found a number of remnant stretches of river wall. All built over now 😦
