Water body baseline
The Environment Agency classifies this water body (Banwell - source to conf R Banwell Estuary) as Moderate ecological status (2019 classification). That is a Water Framework Directive assessment of long-term ecosystem health — plants, invertebrates, fish, chemistry — not a bacteriological measure of whether the water is safe to swim in today. It is shown as context and plays no part in the verdict above.

What this verdict means
Avoid swimming is driven by the strongest negative signals this map tracks: an active sewage discharge affecting this water, or a regulator classification of Poor or a closure. After a discharge ends, waiting at least 48 hours before swimming is the standard advice.
Every verdict here is computed from regulator classifications, sample dates, pollution-risk forecasts, and water-company discharge reports — it is not a water test. Absence of a negative signal is not positive confirmation of safety, and conditions on the day (rainfall, currents, cold) matter as much as water quality. Read how statuses are decided.
