Danube · km 2305.4
Pfelling
Free-flowing The river runs free here, so the level is the constraint: this is where a drought actually binds a hull.
Straubing–Vilshofen: 69 km with no locks and no weirs, the one stretch of German Danube that cannot be regulated at all. If the Danube stops a cruise, it usually stops it here.

low on mean low/high water (MNW/MHW) · normal on navigational reference levels (NSW/HSW) — the publisher's own classification of its own reading.
78 cm below the 295 cm clear-line. Waterlogged clear-line, using an assumed 1.60 m draught.

A Waterlogged clear-line is our own arithmetic: the gauge reading at which the published reference depth, minus the ship's draught and a fixed safety allowance, still leaves a comfortable margin. It is not an operator's decision rule and no cruise line uses it. Computed using an assumed 1.60 m draught unless a cruise line is selected. Reference basis on file: RNW (regulated low water) per KWD 2020.

Official German federal six-week outlook (weekly means) — opens BfG
BfG publishes this as a trend statement in weekly means, not as day-by-day cruise guidance. Open the official product to read BfG's own figures and caveats.
Waterlogged does not reproduce or interpret the values on this page. Same unresolved reuse basis as the 14-day product. Waterlogged does not convert weekly means into per-day levels or passenger probabilities.

Waterlogged does not reproduce or interpret the values on this page. Linking needs no licence; the notice text remains governed by the publisher's terms, so Waterlogged does not scrape it into a report.

The window is the 14 days either side of today's calendar date. Years are ranked by their lowest measured daily mean inside it.
Measured PEGELONLINE/WSV stage data, licensed under Datenlizenz Deutschland – Zero – Version 2.0 (DL-DE/Zero-2.0).
- Measured daily means only; missing dates are omitted and gaps are never interpolated.
- This panel describes historical measurements and fitted seasonality, not a forecast.
- The day-of-year median is the fitted PEGELONLINE climatology in drift_params.json; it is not a projected level.
- Today's daily mean may represent a partial local civil day.
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.

How rain becomes river level
What the measurements show
After rain ends, elevated levels at this gauge decay with a ~16-day summer half-life.
How quickly a departure from normal has faded, historically
- In the fitted winter runoff block, an elevated stage anomaly loses half of its remaining magnitude in about 17.2612 days as it relaxes toward the seasonal median.
- In the fitted summer recession block, an elevated stage anomaly loses half of its remaining magnitude in about 15.6129 days as it relaxes toward the seasonal median.
These are level-anomaly persistence figures fitted on measured stage — how long a departure from the seasonal middle has taken to halve. They are not rain-response coefficients and they do not convert rain into centimetres.
The block names are labels on a fitted split of the calendar, not seasons. The later block extends through the end of the year, so do not read its figure as a description of December.
Educational fitted-parameter explanation only; not a forecast or climate projection.
