The monitoring network on this water

Hydrionis holds 262 values from 2 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.

Monthly mean flow at New Draught at New Draught
Each month's mean discharge as the publisher computed it, which shows the seasonal shape an annual mean flattens away. 1995–2022.
Shading marks when something was recorded, not what caused the line.

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 (3 events)

A shaded period marks when something was recorded, not what caused the shape of the line. Where the two coincide, they coincided.

Documented recordA documented event, compiled from cited sources after it happened. The dates are as good as the record, which for older events can mean the month rather than the day.

About this series

Everything below is a property of the data rather than a rating of it. There is deliberately no single confidence score: how much a gap matters depends on what you are about to do with the series, and only you know that.

Period held19952022
Completeness60.7% of the periods in that span are held. Gaps are drawn as breaks and never interpolated.
Known gaps
  • 7 separate periods inside 1995–2022 hold no value. The longest runs from 2018 to 2020 — 3 years with no reading. They are drawn as breaks in the line and are never interpolated across.
ContinuityThe record begins in 1995 and is not continuous from it: 28 years separate the first value from the last, and 61% 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 3 of them, which makes it a full profile.

Attribution you are required to give

These are conditions of the licences the underlying data is published under. They are obligations to the publishers, not to Hydrionis, and they apply to you directly whether or not you mention Hydrionis at all.

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 New Draught 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.

Method: Count of distinct mayfly, stonefly and caddisfly families in a standardised three-minute kick sample (method BT001). Every record is rolled up to its family through the Environment Agency’s own taxon dictionary before counting, because analysts identify to mixed ranks and counting raw taxa would measure the depth of identification. Records identified no further than the order are excluded.
