The Healthy Harbour Watchers Programme facilitates analyses of water samples from the harbour several times per year. These analyses have produced information sufficient to constrain current baseline water quality in the Otago Harbour based on concentrations of nutrients, dissolved oxygen, and Enterococci counts. Because sampling and analyses are performed consistently over the course of each year, the data can also be used to define spatial and temporal trends in water quality parameters. In the future, Healthy Harbour Watchers data will be used for development of a nutrient-based predictive model for water quality in Otago Harbour, and to inform local government, the general public, and other stakeholders interested in effective management of Dunedin’s water resources.
