What this verdict means
Use caution means at least one signal argues against swimming right now — a discharge in the last 48 hours nearby or upstream, an elevated pollution risk forecast, or a weak classification. The evidence above shows which signal is driving it.
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.
