The water is "so clean" that you have mandatory showers before going in... But it's France, so how would you live without pointless regulations?
People wear all sorts of oils and perfumes and deodorants that should be washed off before swimming.
I was dubious so did a fact check, and it is indeed necessary! Not sure what the reasoning is, I wonder if it's some rule about public swimming which was originally created only for pools? Or maybe there are some wildlife concerns with certain lotions/etc getting in the water.

I wonder if the water from those showers is drained directly in the river ?
Isn't a shower before swimming in a public pool a universal thing? It's always required in France.
