Water level at the Mannheim gauge

On 25/10/2026 at 05:15 the Mannheim gauge read 75 cm, 2 cm lower than 24 hours earlier. Source: PEGELONLINE (WSV).

Gauge Mannheim is on the Rhine at kilometre 424, on the km 410.5–431.5 stretch.

Fairway depth and rule of thumb

The GlW is 155 cm and the fairway depth maintained below it (TuGlW) is 210 cm; after deducting 30 cm of safety margin the official rule of thumb comes out at Mannheim +25. In practice Mannheim +40 is used here, +15 cm against the official rule.

The fairway depth below GlW is what counts as long as no Fehltiefen are reported. Fehltiefen (shortfalls in fairway depth) are published on ELWIS Fehltiefen. The safety margin is not a statutory value and has to be taken on top of the reduced fairway depth listed there.

High water: Marke I and Marke II

At high water Marke I is at 650 cm and Marke II, above which the waterway closes, at 760 cm.
