Overview
Regional and city councils monitor recreational water quality to identify risks to public health from disease-causing organisms and toxic algae. People can then make informed decisions about where, when, and how they use rivers and the marine environment for recreation.
Monitoring network
The map below shows the monitoring sites coloured by the proportion of days predicted as suitable for swimming, based on an indicator bacteria ‘nowcast’ criteria model approach implemented in December 2018.
Scroll/zoom on the map to find areas of interest. Click on a coloured site to see more information. Use the seasons toggle in the top right to compare winter vs summer seasons.
Guide to the site
This online reporting tool provides the results of the field surveillance monitoring data that was carried out during the summer months at 21 freshwater sites and 61 coastal sites from 1 December 2018 to 31 March 2019. We also report winter monitoring for 11 coastal sites, and water quality at 7 popular shellfish gathering sites.
Results of toxic algae monitoring are also summarised here.
Details of methods and guideline comparisons are described in full in the 2017/18 annual technical report (see Brasell and Conwell 2018).
Further details regarding the model, technical reports, guidelines and LAWA can be found here.
