I doubt that Minni, with all due respect. The idea that the water gently rose then gently fell is wrong - it ROARED down those creeks in a flood surge. The pressure and flow involved when the creeks do that is enormous. And you can see some of the debris that got washed down the creek even now, including large tree trunks. If she had simply been placed under the bridge, and the flow and the height of the tide reached her, then she would have washed out into the main river. But if she came down in the flow, from somewhere further up the creek, and the water level was well up above the normal high tide mark, she could easily have just snagged up on those bushes that would have been underwater, and then as the tide receded (those creek floods drop very quickly) and as her body weight gradually came into play (she would have been almost weightless while in the water), she could then have simply rolled down from those bushes to where she was found.
I have doubts about this for a couple of reasons: why would the police send a kayaker, who could only search the mouth of the creek? Surely they would send a car or van, with people who could search ALL the surroundings? After all, they could see under the bridge by approaching from the land, but they wouldn't be able to see the land by approaching from the water. Also, I really doubt that they had his GPS data. First, I'm not sure his iPhone may not have recorded that data if he had location services turned off. But mainly, you may recall that his iPhone data only became available the day prior to his (delayed) bail application.
No - I think the kayaker was just a random kayaker who happened to nose up into the creek. Of course, I could be wrong, too - .....
