On August 31, the 90 meter long passenger vessel Rheinenergie ran aground on the Rhine near Cologne, Germany. The vessel was maneuvering when it touched bottom. Several passengers on board were thrown off their feet or landed awkwardly on the deck. Six were taken to hospital for injuries. Reports state the low water levels on the Rhine were the cause of the grounding. Authorities inspected the vessel the following day and went back into service. No reports of damage or pollution released.
