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 Aberdyfi, the Afon Leri runs 22 km. The lowest 6 km are tidal, where a gauge reads the tide as much as the river. Its gauges hold between 7 and 45 years of readings, and that is what today's levels are compared with.

This is not a flood-warning service. For flood warnings in Wales go to Natural Resources Wales; in England, the Environment Agency. In an emergency call 999. The map cannot see the sea, surface water, drains, or any one address.
