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 Dulais
About this river
From its highest reach down to its mouth near Pwll, the Afon Dulais runs 89 km. The course above is drawn in two weights: the bright line is where Ordnance Survey Open Rivers calls the channel the Afon Dulais, and the faint line, about 23 km of it, is the same water running under another name, past a lake or a weir pool. Its gauges hold between 9 and 23 years of readings, and that is what today's levels are compared with.
