The monitoring network on this water

Hydrionis holds 744 values from 21 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 2 of them, which makes it a profile, not indexed.

Source: PEGELONLINE (WSV)PEGELONLINE — German federal waterway gauges, 26400550. 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.
