Moselle: Cochem ↔ Koblenz

The Moselle between Koblenz and Cochem is canalized, held up by a chain of locks, and that means the low-water anxiety that shapes Rhine and Danube cruising largely doesn't apply here. It's worth saying plainly: on this stretch, low water essentially never disrupts a sailing. That's not a hedge — it's the actual, reassuring truth about this reach.

High water is the real story. When the Moselle rises, this section can suspend sailing on its own — Cochem is tracked as an independent trigger point, not simply inferred from readings further upstream at Trier, because a fast local rise here can close the popular Cochem–Bernkastel run on its own timeline. Lines respond with schedule shuffles, an extra night in port, or occasionally a short coach transfer while levels ease.

There's a second, separate way high water reaches the Moselle: through its mouth. The Moselle joins the Rhine at Koblenz, and when the Rhine itself closes there, it can block Moselle access even if the Moselle's own gauges look fine — a ship simply can't reach or leave the river. That's why this page tracks both the Moselle's own Cochem gauge and the Rhine gauge at the Koblenz confluence: two different rivers, two different ways to be affected.
