The police and PF seem to have concluded that Nicola would have fallen in and essentially drowned, fairly quickly in or very near to the point she landed. This looks like they think she fell in near to the bench. But her friends have emphasised that she’s a very strong swimmer. So she could have fallen in, tried to get to the bank, but failed, so swam and went with the tide further down the river, hoping to find a place where she could climb out. It’s what I’d do.
This link is a paywall, but the headline explains about her friends saying she’s a good swimmer.
A mother who police believe fell into a river was an “incredibly strong swimmer”, a friend has said, as new images emerged of Nicola Bulley on the morning

If this was the case, unfortunately she doesn’t seem to have managed to get out, but this could very easily explain why she wasn’t found in the area in which it is believed she fell. Unless she was unconscious when she fell or became unconscious in the river (maybe hitting her head on rocks), I’m not sure I’d assume she essentially died on the spot. I think she’s got more fight in her than people give her credit for.
