Drought – Tarn and Aveyron move to enhanced alert status

Updated on 08/14/2026

The storms on Sunday, August 9, and Monday, August 10, benefited the basins of the Séoune, Lemboulas, and the eastern part of the department, as well as upstream areas of the Aveyron and Tarn. However, this rainfall remains insufficient to ensure satisfactory water levels across all watercourses.

As a result, the Tarn and Aveyron will be placed under enhanced alert status. The same applies to the Lère, which has been replenished, and the Tescou, which has been replenished.

Following on from previous orders, the Prefect of Tarn-et-Garonne issued, on 14 August 2026, a restriction order concerning water withdrawals from the natural environment. This order takes effect from Saturday, 15 August 2026 at 08:00.
