There are some odd things about this story.
Lots of stories lately of people drowning in canals but they seem to avoid the obvious question which is, why didn’t they just stand up? And the channel depth of canals includes the silt layer which covers the actual bottom, which can make canals a few inches shallower in places. There’s a myth that silt deepens canals, when it does the opposite.
Canals in the UK are still water, and do not have currents. So it’s not like she got swept off her feet by a current.
This story has been all over Facebook lately in the UK. Many people have commented asking why she didn’t just stand up, and that question got a lot of likes, but no actual answers.

Can the bottom be slippery enough for someone to not regain their footing? People can stand up on ice, for example.
There are also plenty of videos of people slipping on ice and eating it over and over again trying to stand up. I don’t know the circumstances of this story to say definitely nothing fishy happened, or definitely something fishy did happen, but drowning in shallow water, in itself, is not necessarily suspicious.
