Burgundy and upper Rhône had virtually no rain and aquifers were low or very low, but Berry had seen improvement, a survey by the official BRGM geological body said.
Southern Alsace is lower than normal and the Sundgau nappe is at its lowest since 1955. Without heavy rain, the situation could turn very difficult in these areas.
Levels are moderately low in Hauts-de-France, Normandy, Nouvelle Aquitaine, eastern Occitanie and western Provence-Alpes-Côte-d’Azur, but aquifers are already falling.
