Reporting of current algal alert is now managed by WaterNSW.
A new alerts level framework for raw waters used as a source for potable supply is available at Water Quality Research Australia.
The role of DPI Water in algal management is to
- Co-ordinate and support the State Algal Advisory Group
- Provide advice on algal issues and the government strategic direction of algal management and planning in NSW
The State Algal Advisory Group provides the over arching policy advice and framework for the management of fresh water and marine blooms. Membership of the State Algal Advisory Group is made up of the relevant NSW State Agencies, NSW local government and the Murray Darling Basin Authority.
A Yellow Springs Instruments water quality sonde was used for the detection of phycocyanin and chlorophyll-a along the Murray and Lower Darling Rivers during 2008-2009. This examined whether the in-situ quantification of phycocyanin by fluorometry could be used to determine the abundance of cyanobacteria. This study found that in-situ phycocyanin fluorometry could be adopted as a tool for cyanobacterial management provided that the equipment used has a comparable performance to YSI and that it not be used in turbid water.

Dr Lee Bowling, Principal Limnologist and State Algal Coordinator in the Environmental Evaluation and Performance Branch of the NSW Office of Water was awarded an international travel grant under the Australian Academy of Science's Scientific Visits to North America program to study developments in cyanobacterial (blue-green algal) management in Quebec, Canada during September 2009.

An analysis of cyanobacterial bloom occurrence in Missisquoi Bay (Québec, Canada)
Cyanobacterial (blue-green algae) are a water quality problem common to many parts of the world, including New South Wales and Quebec, Canada. In 2009 Dr Lee Bowling, Principal Limnologist and State Algal Coordinator in the NSW Office of Water visited Quebec on an Australian Academy of Science travel grant to study cyanobacterial problems and their management there. Since then he has worked in collaboration with colleagues from Quebec to examine cyanobacterial blooms in Missisquoi Bay, one Quebec water body frequently impacted by severe blooms. The outcomes of this work are provided in this report, which enhances the ecological understanding of cyanobacterial bloom occurrence and is relevant to bloom management both in NSW and Quebec.
