Find out about water quality in the Waikato River by clicking on one of the monitoring sites on the map below or using the text navigation. Find out more about our monitoring.

For each site on the river, we show how good the water quality is for:

	Ecological uses (the plants and animals that live in the water)
	Swimming

We also show how each site compares with the others on the river for both ecological uses and swimming.

Find out how the water quality changes between Taupo and Port Waikato.
