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.
