Water quality monitoring - rivers and streams

Waikato Regional Council measures water quality every month at 115 river and stream sites throughout the region. These include the Waikato, Waipā, Waihou and Piako rivers and the many streams that flow into them. We also monitor sites at Lake Taupō and at the streams that flow into it.  

Water quality in rivers and streams is influenced by the surrounding land uses and land management practices. So, here in the Waikato, we find that water quality is generally excellent in our upland bush areas, but it deteriorates markedly in the urban and lowland farming areas.
