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 SBB00537). Rainfall: EA Hydrology gauge 8d954129-924c-47e3-8750-5f29a59617b2. 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.
