not much you can do about that, I'm afraid
So, if possible, get out of the paths of backflow.
The lake is split between France and French-speaking part of Switzerland. In French, the name is Léman. I do think using the local name is better, even more when this local name is acknowledged (en.wikipedia shows both Geneva and Léman).
To me, born and raised in Romandy, "Lake Geneva" feels like "Tokyo Country" for Japan or "California Ocean" for the Pacific.
Lake Léman = Lac Léman = Genfersee = Lake Geneva
There is nothing wrong with the title of the Nature paper: Giant Lake Geneva tsunami in AD 563
May be the reason.
