This record covers 36 days, not a full run of seasons, so “highest” here only means highest so far. It may still be ordinary for this river. One-off spikes are ignored when working out highs and lows, but faults can last longer than that.

This archive holds 3,291 readings over 36 days, back to 28 Sept 2026. Riverbook has been collecting for 3 hours, since 2 Nov 2026. Readings before that come from the OPW’s five-week file.

This gauge appears to be tidal, judged from its name or its recent pattern of readings. Its level rises and falls with the tide, and its highs and lows reflect tides and surge as well as river flow.
