Beverley Brook
3 monitoring stations on this water in England, holding 1,065 values between 1935 and 2025. A named watercourse. The gauges below sit on it, at points its publisher records.
The monitoring network on this water
Hydrionis holds 1,065 values from 3 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.
The seasonal shape
An annual mean says how much water a river carried. A monthly record says when — and on most rivers the difference between a wet winter and a dry summer is larger than the difference between one year and the next.
Taken as the publisher computes it rather than recomputed by Hydrionis from daily values: the publisher knows which of its readings passed validation. Months the gauge did not cover are absent rather than interpolated, and the line breaks where they fall.
What the shaded periods are (4 events)
A shaded period marks when something was recorded, not what caused the shape of the line. Where the two coincide, they coincided.

|---|---|
| How the values came to exist | Measured |
| Period held | 1935–2025 |
| Completeness | 51.6% of the periods in that span are held. Gaps are drawn as breaks and never interpolated. |
| Known gaps |
|
| Continuity | The record begins in 1935 and is not continuous from it: 91 years separate the first value from the last, and 52% of the years between them are held. The span is not the record. |

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 5 of them, which makes it a full profile.
| Signal | Held | Counts |
|---|---|---|
| Gauges holding a real record | 3 | yes, 3 or more |
| Years spanned | 91 | yes, 20 or more |
| Values held | 1,065 | yes, 1000 or more |
| Distinct measurements | 7 | yes, 2 or more |
| Publishers measuring it | 2 | yes, 2 or more |
| Official identifiers | 1 | recorded, not counted |

Where these figures come from
Source: EA — Hydrology Data Explorer API, EA measure bb02cfc2-0819-427b-bb42-80099ce25bc6-flow-m-86400-m3s-qualified. Licence: Open — attribution required (attribution required).
Method: Mean of the twelve monthly means for the year. Computed from months rather than from daily readings directly, so that a year with uneven observation is not weighted toward its best-observed months. Years with any month missing are not published.
Aggregated by Hydrionis from daily mean flow published by the Environment Agency under the Open Government Licence v3.0.
