Rainfall evidence
Daily rainfall at the matched gauge (Austins Bridge) for the spill day and the days before. A spill is dry when every day in the window is ≤ 0.25 mm.

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 SBB00179). Rainfall: EA Hydrology gauge fd8ea26c-8052-48c5-a1bb-bbd5ebbbb3d3_364176. 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.
