Suspected BGA Bloom

MID drains

Southern Rural Water is warning Macalister Irrigation District residents to be aware that there may be Blue Green Algae (BGA) outbreaks in local drains.

"Warm weather, still conditions and less fresh water flow means that conditions are suitable for natural algae outbreaks," said Manager Sustainability, Craig Smith.

"We urge anyone who sees water with algal blooms to avoid contact, and not use it for any domestic purpose, including drinking water for stock or people."

Irrigators who use the drains are encouraged to take extra care to avoid spray drift and inhaling contaminated water.
