¿Al menos 40 departamentos franceses estarán bajo restricciones oficiales de agua el 1 de septiembre?

Por qué: The supplied evidence shows legally binding prefectural arrêtés (posted on the official VigiEau platform) with start dates in late August 2026 and end dates into October 2026, so those orders were in force on 2026-09-01. VigiEau’s historical map/table (snapshot shown) lists many departmental arrêtés (examples with start dates 29/08/2026 and 31/08/2026 and validity through Oct. 2026) and provides PDFs of the arrêtés. Independent news outlets corroborate that dozens of departments were under restrictions in August 2026: Connexion reports 57 departments on “crise” by 20 Aug 2026 and other Connexion pieces and ToutSurMesFinances report many dozens (over 90 departments: alerts or restrictions) in late August; Euronews reported 67 departments in “crisis” as of 9 Aug. The Service-Public and the news stories describe the measures at alerte/alerte renforcée/crise levels as prohibiting or restricting non‑priority uses (garden watering, car washing, pool filling) and in some cases agricultural withdrawals. Taken together the official VigiEau entries (legal arrêtés with validity windows covering 2026-09-01) plus multiple independent news reports establish that at 12:00 CEST on 2026-09-01 at least 40 French departments each had at least one legally binding water‑use restriction in force limiting non‑priority uses.
