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 3,363 readings over 37 days, back to 29 Aug 2026. Riverbook has been collecting for 1 hour, since 2 Nov 2026. Readings before that come from the OPW’s five-week file.
