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 SBB01359). Rainfall: EA Hydrology gauge 723a8fc4-908b-4430-91c7-9990be86540a_363307. 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.
