Apart from the Waikato and Waipā rivers there are three major rivers in the region. These are the:
There are also many smaller rivers and streams.
Waikato Regional Council measures water quality every month at 100 river and stream sites in the region, including five sites on the Waipā River, and at 10 sites on the Waikato River. We also survey stream habitat at 125 river and stream sites, including the plants, insects, fish and other animals that make up stream life in the Waikato region.
Measuring stream health helps Waikato Regional Council to judge the success of our environmental management programmes. We develop policy on how we will address the issues and activities affecting water quality in the Waikato. We also encourage people to understand their place within the environment, to participate in environmental activities and learn about their environment.
