French Groundwater Levels Stable After Winter, But Summer Drought Risks Remain

Despite a wetter winter boosting reserves, experts warn that reduced spring rainfall could quickly reverse gains.

France's groundwater levels are mostly satisfactory, with 60% of reserves above seasonal norms as of March 1, according to the Bureau of Geological and Mining Research (BRGM).
Heavy rainfall in September, October, and January contributed to significant recharge, although February saw below-average precipitation.
Regional disparities persist, with western France experiencing higher-than-normal levels, while southeastern areas like Roussillon and Corbières remain severely depleted from a prolonged three-year drought.
Reactive aquifers, which replenish quickly, are at risk of rapid decline if spring rainfall remains below average, as predicted by Météo-France for March through May.
While current conditions are better than in 2024, experts caution that groundwater levels could deteriorate, increasing the likelihood of summer droughts, even in areas currently showing high reserves.
