Rain eases drought, but soil recovers slowly
The Netherlands no longer has a nationwide water shortage, while low groundwater levels and river flows continue to have consequences.
Recent showers have eased drought conditions in the Netherlands, but have not resolved them everywhere. Rijkswaterstaat warns that groundwater levels, river flows and nature may continue to suffer from the dry summer for months.
At the beginning of September, the Netherlands scaled back its nationwide drought response. Since 3 September, there has been no actual nationwide water shortage, according to Rijkswaterstaat. Water management returned to level 1, ‘threatening water shortage’, because the rainfall deficit had declined and demand for water had fallen.
That does not mean the effects of the summer are over. Rijkswaterstaat reported that regional differences remain substantial. Shipping, agriculture, industry and nature in particular may still experience difficulties. Salinisation of the IJsselmeer also remains a concern for drinking-water companies, because saltier water is less suitable as a source of drinking water.
The delay is mainly underground and in the rivers. According to Rijkswaterstaat, river levels may remain low until the end of the year, while groundwater levels may still need months to recover. A rain shower temporarily makes the uppermost layer of soil wetter, but does not immediately replenish a deep groundwater reservoir.
The origin of the river water also plays a role. The Rhine and Meuse carry water from catchment areas outside the Netherlands. Rain in the Netherlands can therefore provide local relief, while flows at Lobith or in the Meuse basin remain low. For shipping, this may mean that vessels carry less cargo or have to wait longer at locks.
The KNMI described the summer of 2026 as exceptionally warm and dry. The average temperature was 19.3 degrees, compared with a long-term average of 17.5 degrees. At the end of August, the nationwide rainfall deficit was approximately 285 millimetres, while the normal figure is more than 100 millimetres.
A nationwide average conceals important differences. The KNMI reported that the deficit in the south and west was more than 300 millimetres, while the north-east and parts of the east recorded around 50 millimetres. Heavy showers can also bring large amounts of water in a short time without it penetrating deeply into the soil everywhere.
The drought monitor will continue to be published weekly until 1 October. The water authorities are therefore tracking not only rainfall, but also river flows, groundwater, salinisation and demand for water. The current situation is thus not a nationwide crisis, but neither is it a complete return to normal conditions.

Editor's note
The nationwide water-shortage situation has been scaled back, but regional and long-term effects remain demonstrable. The figures for temperature and rainfall deficit are measurements; the expected duration of low river and groundwater levels is a forecast by Rijkswaterstaat.Sources
