Drought Worsens: Loire Records Historically Low Water Levels in July

Orleans – 13 July 2026: The drought in France intensified further by mid-year. The situation is particularly evident on the Loire: according to the Environment Ministry, the river’s natural flows have reached historically low levels for July. The decline is also visible in the riverbed. Following a lack of substantial rainfall and several heatwaves, soils, smaller bodies of water and local water reserves are coming under increasing pressure.

The government describes the dry spell as exceptionally early and intense. Soil dryness has now spread across mainland France and Corsica. Since the beginning of June, water levels and flows in many rivers have been falling rapidly. Almost one-third of monitoring stations are recording figures below the previous lows of the past 20 years for this time of year.

According to data from the state platform VigiEau, 98 departments are affected by measures to monitor or restrict water use. On Monday, the Environment Ministry put the number of departments with restrictions in force at 97, including 41 at the highest crisis level. The differing figures are explained by different collection times and the dynamic development of local regulations.

For the Loire, low-flow support was started earlier than in previous years. Water is being released from reservoirs in a controlled manner to support minimum flows in the river system. Reserves in the large dams were built up at the beginning of summer, but must be used earlier due to the persistent drought. This increases pressure on water management until the end of summer.

Depending on local conditions, prefectures can restrict agricultural irrigation, the filling of private swimming pools, vehicle washing, garden watering and certain industrial withdrawals. The aim is to safeguard drinking water and essential public services, while protecting rivers, wetlands and other sensitive ecosystems. Restrictions have already been tightened in several regions.

The Massif Central region is particularly affected, as its water bodies play a central role in many major river systems. Groundwater levels are also being monitored more closely. Although some reserves were better filled after favorable spring recharge than during the dry years of 2022 and 2023, rapidly responding aquifers in Auvergne, Limousin and Grand Est could decline significantly in the coming weeks.

The consequences extend beyond water withdrawals. Higher water temperatures and low flows place stress on fish and other aquatic organisms. The ministry also points to risks for aquaculture, agriculture and certain industrial operations. Authorities intend to assess the situation weekly at the river-basin level in the future. Residents are asked to check the rules in force in their department and use water sparingly.
