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

Gauge proximity
Outlet (red) vs matched rain gauge (blue), 7.0 km apart. Closer means the rainfall reading is more representative of the overflow.

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 SBB00295). Rainfall: EA Hydrology gauge e7e2f7d4-f497-4adc-b077-c20bc2dcedfa. 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.
