Water quality update - Barrett Weir and Rivermouth

Water quality monitoring ongoing across local swimming areas

Margaret River Rivermouth – health warning lifted

Good news! Recent water sampling this week shows satisfactory E. coli levels at the Margaret River Rivermouth. As a result, the health warning has been removed.

Conditions in natural waterways can change quickly, particularly after rainfall. Please continue to use your own judgement when swimming.

Barrett Weir – swimming not recommended

Recent testing shows the water at Barrett Weir is not safe for swimming right now.

This is likely due to still and shallow water, which can allow germs to build up. Wildlife such as birds and other animals can also introduce bacteria, and when water isn’t flowing, water quality can change quickly.

Please avoid swimming at this location for now and take care of yourself, your pets and visitors when accessing natural waterways.
