Fosse Dionne - tonnerre

​The average daily discharge is 311 liters per second

One of the places I have visited many times in France is a beautiful little village called Tonnerre. 2012 - 2019 Until the pre-Covid period, it was usual to go with some paintings and create and chat.

​The Fosse Dionne is a karst spring, in Tonnerre in the Yonne department of France. It is fed by the rainwater on the surrounding hills as well by at least one subterranean river.
