In 2011, the first dissolved oxygen (DO) sensor was installed at a hydrometric site in Deniliquin to capture information for improved management of low dissolved oxygen black water events that frequent the area. Nine other strategically placed DO sensors were installed during the same time. In the decade that followed, more DO sensors were installed in other NSW rivers bringing the total to 32 Hydrometric sites with DO sensors that are maintained by WaterNSW. Blue-green algal reporting and management have also evolved over the same period to include custom script satellite imagery for detecting phytoplankton blooms in NSW water storages. This paper refers to some of the challenges that were experienced as well as the benefits of having invested in these technologies. Some of the challenges included overcoming limited resources, upskilling staff to use new technologies and integrating new layers of information into the existing processes to manage low dissolved oxygen events and algal blooms.
