Dry spill

Evidence strength

Medium confidence
  • Dry across a 4-day antecedent window
  • Rain gauge close (≤5 km)
  • Short discharge (<1 h) — weaker signal

Rainfall evidence

Daily rainfall at the matched gauge (Mardon Down) 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 SBB00152). Rainfall: EA Hydrology gauge 323b21d8-c9a4-4681-bc5c-62d7337993ac. 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.
