- Yes — the treatment works' own overflow stayed shut that day, so capacity was available. Avoidable.

⚠ Coastal / tidal location — very short discharges around high tide can be monitor artefacts; corroborate with tide times before relying on short events here.
Method & provenance. Dry/wet classification is decided by rainfall at the nearest EA gauge — ≤ 0.25 mm on the spill day and each preceding day of the window (how we classify). Spill data: Environment Agency EDM (outlet SBB00776). Rainfall: EA Hydrology gauge 9dba2bf3-f5ea-4616-ac8e-dce16dbc0dc8. A dry spill is precautionary evidence of a likely fault, not proof of an offence — we test the rainfall, not the works' flow. Generated by River Hub.
