This month of September, continuing from the summer, is marked by a very significant rainfall deficit. Precipitation is almost absent, temperatures are exceeding seasonal norms, and soil moisture remains very low. This situation is expected to persist in the coming weeks without significant improvement.
The flow rates of the lower Arve river are thus recording very low levels, while other sectors of the department show no improvement.
In response to this situation, the Prefect has decided that the current restriction measures in place in the commune of Taninges, which is part of the Arve Median basin, will be extended until October 31, 2026.
