This chart illustrates the evolution of the share of groundwater reserves in deficit in France in 2018, 2022, and 2023. It can be observed that in 2018, groundwater reserves were recharging at 80 percent during the spring, with their deficit increasing only at the end of the summer season. In contrast, in 2022, the drought prevented the reserves from filling up in the spring, resulting in nearly three-quarters of the groundwater reserves being in deficit at the beginning of the summer. On February 20, 2023, a record 85 percent of the groundwater reserves were in deficit.
