This record covers 37 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 3,369 readings over 37 days, back to 25 Aug 2026. Riverbook has been collecting for 8 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.
