I must admit that the last time we swam in the Ardeche in 2015 we were asked to stay out of the water by the lifeguard, because of 'pollutants in the water caused by high levels of run off fertiiser'. It shows how vigilant we need to be about things like this.
However, just up river in the Chassezac, we were swimming in the river daily until the 9th September, with no untoward effects at all.

Good grief! We were there in late August/early September, with a young dog who loves swimming. We were totally unaware of this blue-green algae risk, before reading this thread. What with processionary caterpillars and now this, it makes us stop and think whether our dog would be safer left at home, with friends!
Don't forget to leave a review of the French and other European campsites you have visited!
As I said, we were swimming in the Chassezac (a tributary which joins the Ardeche south of Ruoms). Where people swim too then warnings will be issued about the water quality, so rather than avoiding rivers and beaches altogether, just let the dog swim in areas where people are swimming too.
This is just another 'risk' where you weigh up the likelihood of the combination of rainfall, sunshine, and temperature which causes algal blooms, against the benefits to your dog of keeping cool.
There are always risks of one sort or another wherever you do, and avoiding all risks simply isn't possible.
