Lahn
26 monitoring stations on this water in Germany, holding 887 values between 2026 and 2026. A named watercourse. The gauges below sit on it, at points its publisher records.
The monitoring network on this water
Hydrionis holds 887 values from 26 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

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 1 of them, which makes it a profile, not indexed.
| Signal | Held | Counts |
|---|---|---|
| Gauges holding a real record | 2 | no |
| Years spanned | 1 | no |
| Values held | 887 | no |
| Distinct measurements | 2 | yes, 2 or more |
| Publishers measuring it | 1 | no |
| Official identifiers | 1 | recorded, not counted |
Where these figures come from
Source: PEGELONLINE (WSV) — PEGELONLINE — German federal waterway gauges, 25800100. 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.
