Can I swim at Poole Harbour Lake?

Poole Harbour Lake was rated Excellent for 2025 — the highest of the four grades in the Bathing Water Regulations. That grade comes from bacterial samples taken over several seasons, so it describes the beach's record rather than the water on any given day.

The Environment Agency issues a pollution risk forecast for this beach every morning during the bathing season, and the water company publishes the status of its storm overflows every few minutes.

The regulator records this as a bathing water whose quality can be affected by heavy rain, which is why rainfall in the last 24 hours is shown above.
