Levels at the Kaub location in Germany hit 201 centimetres and have been steadily declining since late June, the data showed.
Oil barge brokers said the low water levels meant barges were leaving the Amsterdam-Rotterdam-Antwerp refining and storage hub to inland locations not fully laden.
Water levels along the river hit a record low of 25 cm in October, which led to oil product shortages in Germany and Switzerland.
