Dry spill

Evidence strength

Low confidence
  • Dry on the EA 1-day window
  • Rain gauge close (≤5 km)
  • Short discharge (<1 h) — weaker signal

Rainfall evidence

Daily rainfall at the matched gauge (Bickington) 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), 4.9 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 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.
