Drought: almost all the municipalities of Tarn-et-Garonne are restricted in the use of water

the essential
The showers of the last few days have not changed anything. In Tarn-et-Garonne, river flows have dropped significantly after a dry spring and the recent heat wave. The prefect has just issued a decree limiting water withdrawals which comes into force this Saturday, June 25 at 8 am.

The drought is gaining ground in the Tarn-et-Garonne and it is not the rainy and stormy passages of recent days that have changed the situation. “During the last decade, the episode of heat followed by the heat wave has caused the flow rates of all the rivers to drop, including on the major hydraulic axes”, notes the prefecture. She informs that “low water support was activated on Monday on the Tarn (5.5 m3 / second) and reinforced on the Aveyron, the Tescou and the Neste system”. Thus, the prefect of Tarn-et-Garonne issued a decree on Thursday limiting water withdrawals which will take effect this Saturday, June 25 from 8 am.

This decree concerns, to varying degrees, almost all of the 195 municipalities in the department. Only 10 of them are not subject to any restriction measures for the time being: Puylagarde and Espinas in Quercy-Rouergue; Auterive, Gimat, Goas, Gramont, Marignac and Maubec in Lomagne; Gasques and Saint-Clair in the Deux-Rives.
