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 Wye
About this river
From its highest reach down to its mouth near Old Passage, the Afon Gwy runs 250 km. The lowest 25 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 Afon Gwy, and the faint line, about 102 km of it, is the same water running under another name, past a lake or a weir pool. Its gauges hold between 1 and 41 years of readings, and that is what today's levels are compared with.
- Pant Mawr - a rain gauge near Llangurig, not a river level
- Llangurig - a rain gauge near Llanidloes, not a river level
- Rhyader STW - a rain gauge near Rhayader (Rhaeadr Gwy), not a river level
- Tintern Abbey Mill - on the tidal Gwy at Brockweir, reading 3.33 m. What a gauge reads here is the tide as much as the river, so it is not ranked against a record
