The objective of this study is to describe the conditions which lead to cyanobacterial blooms and from this information identify means of predicting, detecting and managing cyanobacteria in source waters. The site used as a case study was Myponga Reservoir in South Australia (S 35 24. 13. E 138 25. 13.). The reservoir is 36m deep, has a volume of 26,000 ML and catchment area of 124 km2. Landuse in the catchment is predominantly dairy and beef grazing. The reservoir is the site of a CRC Water Quality and Treatment study on artificial destratification using a bubble plume aerator and two surface mounted mechanical mixers are operated for six months each year. As part of this study two meteorological stations with thermistor chains have been permanently deployed in the reservoir to record physical data at 10 minute intervals. Includes 24 references, table, figures.
