Swimming Water Quality

The map below provides a summary of monitoring results from more than 80 popular coastal, river and lake recreation sites around the Bay of Plenty.  Sites are monitored for faecal contamination (bacterial monitoring) from October to March each year and for toxin-forming algae species (algal bloom monitoring) from October to June each year. Click on the area of interest for more detailed information.

You should avoid swimming in rivers for 48 hours (two days) after heavy or prolonged rain. This is because the water can be contaminated by farm and urban run-off.

If you suspect an algal bloom is present, don't swim or take part in an activity that may result in accidental consumption or exposure to water affected by algal blooms.
