The percentile is where a gauge's latest reading sits in its own record of readings, not how full the channel is. A river sits low most of the time, so a high percentile takes surprisingly little water: at Beddgelert on the Glaslyn, with thirty-six years of record, the ninety-fourth percentile is about 1.05 m - 1.38 m below the highest level ever recorded there.
The course of the River Western Cleddau
About this river
From its highest reach down to its mouth near Little Milford, the Western Cleddau runs 31 km. The lowest 5 km are tidal, where a gauge reads the tide as much as the river. The course above is drawn in two weights: the bright line is where Ordnance Survey Open Rivers calls the channel the Western Cleddau, and the faint line, about 17 km of it, is the same water running under another name, past a lake or a weir pool. Its gauge holds 1 years of readings, and that is what today's level is compared with.
- Mathry - a rain gauge near Mathri, not a river level
- Haverfordwest - on the tidal Western Cleddau at The Marsh, reading 0.66 m. What a gauge reads here is the tide as much as the river, so it is not ranked against a record
