Drought in the Southwest: alerts and restrictions in November 2026

In late October 2026, an environmental elected official from Lot-et-Garonne warns of a risk of a drinking water supply disruption in the south of the department, while restrictions persist in Tarn-et-Garonne and a dam in Ariège runs dry. In early November, the drought forces the extension of water releases toward the Garonne beyond October 31, and Voies navigables de France suspends navigation on the Canal du Midi starting November 9. The Neste system remains in maximum crisis in the Gers, and several municipalities, such as Lanne-en-Barétous and Ustaritz, experience water supply difficulties. On November 12, the Adour-Garonne water agency warns of a situation never seen in November, with tap water no longer guaranteed in certain areas, and the drought also threatens future navigation on the Canal du Midi.
