Extreme Drought Cripples Dutch Waterways, Shipping Operations Severely Limited

Extreme drought in the Netherlands has resulted in historical low water levels in major rivers and canals, severely affecting inland navigation. Rijkswaterstaat reports that the Rhine has never had such low water flow, and the Maas also has reduced discharge. This prolonged dry spell is expected to continue, with water levels potentially remaining low until December.

Impact on Shipping

The sluice in Weurt, a vital link between the Waal river and Nijmegen harbour or the Maas-Waalkanaal, is experiencing critical water shortages. One of its two sluices has been closed due to insufficient water depth. The remaining operational sluice has only 1.65 meters of water, which is adequate for empty vessels but too shallow for ships carrying cargo, which typically require at least 2.70 meters.

Broader Drought Effects

Rijkswaterstaat's weekly Drought Monitor indicates that the current situation is "very special," despite past dry periods in 1976, 2003, and 2018. National precipitation deficits are projected to match 2018 levels of around 300 millimeters, with some regions already exceeding 400 millimeters. Groundwater levels are extremely low, and the IJsselmeer water level continues to drop. While drinking water supplies are currently stable, they are being closely monitored. Water managers are developing scenarios for issues like increasing saltwater intrusion and falling IJsselmeer levels.

Causes and Outlook

Climate scientists attribute the current extreme drought to climate change, characterized by more frequent extreme heat and reduced rainfall. The consequences include harm to flora and fauna and economic damage due to hindered shipping. While some rain is forecast, it is unlikely to be sufficient to replenish the waterways. Water managers are implementing measures to retain and distribute water, but regional systems are struggling to meet demand, leading to widespread restrictions on water usage.
