Monitoring the quality of rivers and streams in the Waikato

Our rivers and streams are influenced by the surrounding land uses and land management practices. Water quality is generally excellent in upland bush areas, but deteriorates markedly in urban and lowland farming areas.

Waikato Regional Council regularly monitors and reports on the quality of our region's river and stream resources, and the pressures that face these waterbodies and the plants and animals that rely on them for habitat.

Our rivers and streams indicators summarise the results of our science and monitoring programmes, and provide a holistic report on the state of the Waikato region's environment.

We regularly monitor river and streams at a number of sites throughout the region.
