Severity & context

Bathing water: Dartmouth Castle and Sugary Cove; Warfleet Creek, Dart Estuary
Shellfish water: Not Applicable
Ahead of the works: Unknown (no works overflow data)

⚠ Coastal / tidal location — very short discharges around high tide can be monitor artefacts; corroborate with tide times before relying on short events here.

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 SBB00755). Rainfall: EA Hydrology gauge 9dba2bf3-f5ea-4616-ac8e-dce16dbc0dc8. 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.
