The monitoring network on this water

Hydrionis holds 1,213 values from 13 gauges on this water. Discharge is a property of a gauge and its reach, not of this water as a whole, so this page reports the network and its records rather than a single figure.

How these gauges were attached to this water

Named by the publisher Each gauge here names this water in the publisher’s own station record. Hydrionis has not inferred the connection from station names.

What this record holds

Hydrionis decides which waters get a page, and which of those are offered to search, from what is actually held rather than from how the page reads. Five signals are counted; this record has 3 of them, which makes it a full profile.

No bulk download is offered here, which is a licence position rather than a product one: at least one contributing publisher does not permit redistribution. The values can be read on the page, cited, and pointed to at source.

Attribution and citation

Suggested citation for Hydrionis

Hydrionis (2026), Main gauge records, accessed 2026-10-05, hydrionis.com/waters/germany-main/

Cite Hydrionis where you rely on the compilation, the normalisation, the eligibility judgements or a chart. Where you use an unmodified published value, the publisher’s attribution is the one that is required; crediting Hydrionis as well is welcome and is not something Hydrionis can require of you.

Recommended, not required. Hydrionis does not claim rights over unmodified public data it relayed, and doing arithmetic on somebody else’s measurements does not make them Hydrionis’s. Cite the version and the access date: the Main gauge records changes as publishers release and as methods are revised, and a citation without both cannot be checked later. Full guidance is on cite and reuse.

None of the contributing licences requires attribution. Crediting the publishers is still good practice and they are listed above.

Source: PEGELONLINE (WSV) — PEGELONLINE — German federal waterway gauges, 24900108. Licence: Open.

Method: Daily mean computed by Hydrionis from the fifteen-minute discharge record published by PEGELONLINE. Days with fewer than 72 of the expected 96 readings are not stored rather than averaged from a partial day.

Discharge is a property of this gauge and this reach, not of the river as a whole. Two gauges on the same river can differ by an order of magnitude.
