Advisory Note - Rainfall‑Affected Water Quality

Don’t swim in lakes, rivers, and beaches within 48 hours of significant rainfall!

Swimmers are urged to stay up to date on the quality of their favourite South Canterbury/Canterbury lakes, rivers, and beaches to confirm they are safe to swim this summer.

When you’re heading for a swim, don’t forget to look out for the water quality information signs or visit ‘Can I Swim Here?’ section of the Land Water Aotearoa (LAWA) website at www.lawa.org.nz to view the latest information.

Swimmers should avoid getting in the water within 48 hours of significant rainfall as heavy rain flushes contaminants from urban and rural land into waterways, reducing the quality of water within a short period of time – even at sites that generally have good water quality. Check the water is clean and clear before taking a dip.
