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.
