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: SEPASEPA water environment data, 14923. Licence: Open — attribution required (attribution required).

Method: Monthly mean computed by Hydrionis from SEPA daily mean flow. Months with fewer than 20 days of record are not published rather than averaged from a partial month.

Flow is a property of this gauge and this reach, not of the river as a whole.
