Rhine · km 362.3

Maxau

Held by locks Level held by locks. Weirs keep a working depth through a drought, so the risk on this stretch is high water and lock operations — not low water.

Upper Rhine near Karlsruhe, behind the barrage chain: a low reading here closes nothing. Our judgment is that it is still worth watching, because it is the first place an Alpine recovery shows up.

low on mean low/high water (MNW/MHW) · normal on navigational reference levels (NSW/HSW) — the publisher's own classification of its own reading.

299 cm below the 620 cm first high-water mark (speed and wash limits, and the room under the bridges starts to run out).

The barrage chain holds the depth in a drought — but the locks still close at high water. Drought-proof is not flood-proof.

Official forecasts and notices for this gauge

Linking is not endorsement. The publisher controls its own page, its own values and its own terms.

  • Official German federal 14-day water-level forecast — opens BfG

    The German federal hydrology institute's own daily water-level forecast for the Rhine and other supported gauges, with BfG's own uncertainty ranges and caveats.

    Official external site — leaves Waterlogged. Published by Bundesanstalt für Gewässerkunde (BfG). Link checked 2026-08-02.

    Waterlogged does not reproduce or interpret the values on this page. BfG's catalogue metadata asserts CC BY 4.0 but the delivery channels carry no unambiguous grant, so Waterlogged links to the forecast rather than copying, dailyising or scoring its values.

    The official notices channel for commercial navigation on the German waterways: closures, lock works and high-water restrictions in the authority's own wording.

The same-date history panel for this gauge is not available in this build.

This is measured history, not a forecast and not an estimate of disruption probability.

Rain in the next 14 days

Status: rain forecast not yet enabled. Waterlogged shows forecast precipitation only under a paid Open-Meteo commercial contract, and no contract key is configured on this deployment. The official services linked below publish their own rain forecasts.

Rain may slow a fall or create a rise after losses and routing. Waterlogged does not convert this forecast into gauge centimetres or a cruise-disruption probability.

Source, licence and limits

Upper Rhine reference near Karlsruhe. Carried as CONTEXT for LOW water in v0: its reach (upper_rhine) is classed impounded, so Maxau cannot make a low-water call. Its high-water marks are live — an impounded reach still closes at HSW.
