“It is especially upstream” and the downstream consequences may be more damaging, similar to 2016, according to Jean-Marc Dolmiere, deputy director of the monitoring body of water Vigicrues course.
At the root of this situation, the rainfall in the upstream of the Paris basin, the Yonne, the Marne …

“These regions have taken a lot of water these last seven days, knowing that the soil was already saturated,” says Mr. Dolmiere. “The water rises upstream of the Marne, then it starts to go down, and joined the Seine” .

Of “significant excesses” were also reported Tuesday on the basin of the Seine in particular upstream of the Marne, and the Yonne, according Vigicrues that scans 22,000 km of rivers – complex operation conducted through “scales relative” , the most famous installed at Austerlitz bridge.

“The situation is serious but there is no need to agonize unduly today” , commented the Secretary of State Ecological Transition Poirson Brown, while his colleague Sébastien Lecornu called for “prudence” .
