It also counts as YES if an event is moved to a venue other than the Seine river ahead of time because of water quality concerns.

Looks like you're right. I had assumed the market was created more recently but it's almost a year old. Thanks @Pob for the prescient market...

Monday's training session in the Seine was canceled due to water quality, according to L'Equipe:
The first event in the Seine is supposed to be Tuesday (like a bit over 12 hours from now).

I assume a practice session doesn't count as an "event", but not looking great.
According to a report published by the Paris region and mayor's office, analysis shows the water does 'not meet the standards' set for the 2024 Olympic Games' open-water events, citing the presence of two kinds of fecal bacteria, including E. Coli.
If the river is too polluted when the Olympics kick off, plan B is to postpone the open-water swimming events for a few days – not to move them to a new location.
