Rhine & Danube water levels today

Stage at 79 river gauges on the Rhine, Moselle, Main and Danube, from Germany's federal waterways agency (WSV) and its Austrian partners — the gauges that decide whether barges and river cruises sail fully loaded, half loaded, or not at all.

Every gauge, colored by its own reference marks

Levels are centimeters above each gauge's local zero, so colors — not raw numbers — are what compares across stations. Red means the gauge is under its published low-water reference (GlW in Germany, RNW in Austria): fairway depth is no longer guaranteed there and loaded vessels start lightening.

How to read these numbers

A European river gauge reports stage: centimeters of water above that station's own historical zero point, an arbitrary local datum. A reading of 40 cm at Budapest and 140 cm at Duisburg says nothing about which river is fuller — and at very low water, readings below zero are normal. What makes a reading meaningful is the gauge's own official reference marks: the low-water reference (GlW on German waterways, RNW on the Austrian Danube) below which fairway depth is no longer guaranteed, mean low and high water (MNW/MHW), and the highest navigable level (HSW), above which shipping stops. Every color on this page comes from those published marks — none of the thresholds are ours.

Reference marks are the agencies' published characteristic values. The lower Danube — Slovakia to the delta — is in the pipeline. Sources and computation rules: data & methodology.
