Authorities have issued an urgent health warning for a popular Western Australian swimming spot, urging summer holidaymakers to stay out of the water at Drakesbrook Weir.
Health Hazard Detected in Popular Swimming Spot
The Shire of Waroona has confirmed that recent water quality testing at Drakesbrook Weir has revealed dangerously high levels of harmful bacteria and organisms. The results, which prompted the immediate warning, show elevated concentrations of E. coli, enterococci, and thermophilic amoebae.
While the specific type of thermophilic amoeba found is not the brain tissue-destroying Naegleria fowleri—which has been a concern at the weir in previous years—the shire is taking no chances. A spokesperson for the local government has strongly advised the public against any water contact.
Official Advice: Stay Out of the Water
"We're asking people to avoid swimming, wading, or having contact with the water until we receive the next set of results," the Shire of Waroona spokesperson stated. "This is a short-term precaution, and we will keep you informed every step of the way."
The warning, issued on 20 January 2026, has been backed by WA Health. A state health department spokesperson confirmed they are supporting the local government's management of the public health risk, reiterating the call for locals and visitors to steer clear of the weir.
Precautionary Measures and Ongoing Monitoring
In response to the test results, temporary advisory signs have been erected around Drakesbrook Weir. The Shire has committed to continuing its water testing regimen and will publicly release further results as soon as they are available.
This health alert compounds existing issues at the site. The shire was forced to dock the popular floating pontoon in early December due to water levels being too low, limiting recreational options even before the bacterial contamination was confirmed.
For now, the message from all authorities is clear: Drakesbrook Weir is off-limits for swimming and water play until further notice, casting a shadow over summer holiday plans for the area.
