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 The Roe, the River Elwy runs 30 km. Its gauge holds 42 years of readings, and that is what today's level is compared with.
- St Asaph - a rain gauge near The Roe, not a river level
- St Asaph Spring Gardens - published as a height above sea level rather than as a river level, so it is not comparable with the rest
