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 SBB00393). Rainfall: EA Hydrology gauge 31653dd5-c1ed-4091-a860-5e8d25936861. 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 Teign Data.
