Levels rose in reactive water tables and in the areas that received the most rainfall, while the levels in passive water tables and areas that experienced little rainfall continued to fall or started to stabilise.

The situation in October was satisfactory across a large part of western France. This area is still benefiting from last winter's abundant recharge, in addition to the inflows from the early stages of this recharge period. Water table levels are particularly high in the Adour-Garonne basin and in Brittany.

The state of the water tables in the east of France remains poor. Levels are low to very low in the Grand-Est, Bourgogne-Franche-Comté, Auvergne-Rhône-Alpes and Limousin regions. However, the recharge has started and the situation is slowly improving.

The trends at the end of this year will depend on rainfall. The recharge should start to occur across all water tables and the situation is expected to improve.
