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 Broadway, the River Taf runs 60 km. The lowest 20 km are tidal, where a gauge reads the tide as much as the river. Its gauges hold between 23 and 41 years of readings, and that is what today's levels are compared with.
