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.

About this river

From its highest reach down to its mouth near Rhyl (Y Rhyl), the River Clwyd runs 59 km. The lowest 8 km are tidal, where a gauge reads the tide as much as the river. Its gauges hold between 1 and 39 years of readings, and that is what today's levels are compared with.
