About this spot

Hatchmere is a small lake and nature reserve on the edge of Delamere Forest in Cheshire. It is unusual in having had a recognised swimming arrangement with the wildlife trust, which is why it is still widely listed as a wild swimming spot.

Storm overflows nearby

None of the storm overflows within 5 km with an up-to-date reading are discharging. Heavy rain makes combined sewers overflow into rivers and the sea by design, so this changes with the weather.

These are the water company’s own reports of when an overflow is operating, not a measurement of the water at this spot. A discharge into a river some distance away may never reach here; a quiet list does not mean the water is clean. The swim status above comes from the bathing-water monitoring body and does not use this data.
