Blue-Green Algae

Sunday 29 March 2020

The red alert for blue-green algae remains in place for the  Murray River, from downstream of Merbein Pump Station to Lock 9.

Rural customers in Merbein irrigation district are supplied from the Merbein Pump Station.  There is no red alert currently in place for these customers or private diversion customers upstream of the Merbein Pump Station.  Tanks do not need to be isolated however should remain topped up and customers be prepared to isolate should levels increase.

Private diversion customers downstream of Merbein Pump Station remain in the red alert area and are advised to keep tanks isolated.

Blue-green levels are fluctuating in Lake Cullulleraine and a high caution advisory notice remains in place for this area, with customers advised to isolate tanks as a precaution.  This applies to all customers taking or supplied with water from Lake Cullulleraine, including those in the Millewa district area and townships within it (eg. Werrimull, Meringur, Lake Cullulleraine and other areas).

WaterNSW and Lower Murray Water will continue to monitor water quality along the river impacted by the algal bloom and report the results as they become available.

Signage has been erected in strategic locations along the riverbank and at Lake Cullulleraine advising recreational users that harmful algae may be present in the water.

SMS messages have been sent to those Lower Murray Water rural customers registered to receive SMS, within this affected reach of the river and Lake Cullulleraine, advising them to isolate tanks.

If you are an LMW rural customer and are unsure whether these alerts/cautions affect your rural water supply, call our Mildura office on 03) 5051 3400 and select Option 9.

We monitor levels of Blue-green algae in the River within our service region. Rural customers can register to receive SMS update alerts by contacting our office.

We are a convening agency within the region for Blue Green Algae (BGA) monitoring and reporting.

The monitoring of the Murray River for BGA is undertaken by staff from the New South Wales Department of Environment and Water and is reported back through the Sunraysia Regional Algal Coordination Committee.
