Rhine remains at historic low after exceptional drought
Water managers call the discharge exceptionally low, but distinguish between a daily record and the absolute record low.
After an exceptionally dry summer, the Rhine continues to carry far less water than usual. Measurements by Rijkswaterstaat and the KNMI show that the river has reached historically low levels, while not every record mentioned concerns the same measuring point or period.
At the end of July, Rijkswaterstaat reported that the Rhine at Lobith had never stood so low. The KNMI later qualified that picture by distinguishing between the lowest discharge for a particular calendar day and the absolute record low in the complete measurement series. Such differences matter: a daily record says something different from the lowest value ever measured.
At Lobith, discharge on 6 August 2026 was 655 cubic metres per second, according to the KNMI. For that time of year, this was the lowest value in the measurement series dating back to 1901. The absolute record low in that series is 620 cubic metres per second, measured in November 1947. That record had therefore not been broken in early August.
The low discharge is the result of prolonged drought in the Rhine basin. Exceptionally little rainfall fell there, particularly in April and July. The KNMI also refers to research showing that climate change has increased the likelihood of the European drought. This is a model-based attribution of probability, not a measurement that fully explains one individual dry day.
The consequences extend beyond shipping alone. Low river discharge makes waterborne transport more difficult, limits the availability of freshwater and increases the risk of salinisation in coastal areas. Agriculture, nature and the cooling of installations may also be affected when less water is available.
At the beginning of September, Rijkswaterstaat reported that there was no longer an actual water shortage nationwide, but that the effects of the drought would remain noticeable for a long time. In the water report of 26 September, the Rhine and the IJssel were still listed as lower than normal for the time of year. The situation had therefore improved from its low point, but had not returned to normal autumn discharge.
The low Rhine is also forcing water managers to make choices about distribution among shipping, agriculture, nature, drinking water and industry. Rijkswaterstaat stresses that such problems must be addressed at the level of the entire river basin, because rainfall and water use in several countries together determine the Dutch river level.
One story, several perspectives
What is established
- The Rhine has reached historically low discharges.
- The low water level affects multiple water users.
- Water managers must distribute available water among different interests.
- River discharge is influenced by conditions throughout the entire river basin.
Left
Arguments Water must primarily be distributed according to ecological limits and essential public needs. Shipping, intensive agriculture and industry must not have unlimited claims on an increasingly scarce resource.
Values Nature restoration, public responsibility and intergenerational justice.
Consequences This may lead to stricter extraction rules and higher costs for sectors that use a great deal of water, but it protects ecosystems and drinking-water supplies.
Centre
Arguments The government must apply a transparent order of priorities and invest in buffers, international agreements and better measurement data. No sector can be structurally exempted.
Values Balance, practicality and long-term planning.
Consequences A combination of temporary restrictions, infrastructure and European cooperation can limit damage without permanently giving priority to one interest.
Right
Arguments The emphasis is on adaptation and room for economic activity. Businesses and farmers must develop their own solutions through innovation, storage and more efficient use, while the government primarily provides predictable rules and infrastructure.
Values Ownership, economic continuity and technological solutions.
Consequences This approach may accelerate investment, but can disadvantage vulnerable nature and smaller users when water rights are organised mainly around economic value.
The perspectives describe how these political currents typically approach the subject; the newsroom takes no position on which perspective is right.

Editor's note
The river has reached historically low values. The article carefully distinguishes between the lowest level for the time of year and the absolute record from 1947; the current water level does not everywhere match the earlier low point.Sources
