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 Banwy
About this river
From its highest reach down to its mouth near Eglwys-fach, the Afon Einion runs 312 km. The course above is drawn in two weights: the bright line is where Ordnance Survey Open Rivers calls the channel the Afon Einion, and the faint line, about 6 km of it, is the same water running under another name, past a lake or a weir pool. Its gauge holds 19 years of readings, and that is what today's level is compared with.
