Auckland’s freshwater resources include around 16,500km of permanent rivers, 72 lakes, and extensive groundwater sources. These resources provide a diverse range of habitat for birds, plants, fish and invertebrates as well as supporting agriculture and the high value recreational areas loved by Aucklanders.

Our Freshwater Monitoring Programme aims to describe the quantity and quality of the region’s freshwater resources and assess the effects of our use and environmental stressors on them. Freshwater quantity, quality and ecology are monitored by Auckland Council at approximately 100 river, 29 lake, 80 rainfall and 79 groundwater sites.

Many of the rivers, lakes and groundwater sites we monitor are degraded to some extent, although there have been improvements in the last decade. Many of our urban and rural streams have the potential for further improvement.
