And a good illustration of how a novice can get into trouble on easy water when the hazard is very easy to see, well ahead of encountering it. I have run past that pile dike 20 or 30 times, and never been in a position where I might get strained, even during a strong ebb.
Very glad the 911 operator was on her toes, and that the lady was rescued successfully.
A basic knowledge of ranging, and maintaining a sharp lookout would have prevented this accident. That is not a tricky passage.
This made Fox News in the US, complete with interviews with both the 911 dispatcher and her mother. She used a small canoe to make the rescue. That had to take skill to not roll the canoe. Maybe there was room to get the canoe facing upstream between two pilings.
