Rivers & Lakes
~ Ngā awa, ngā roto me ngā rohe kōreporepo



Hawke's Bay has a number of lakes, the largest of which is Waikaremoana in Te Urewera. 

For water quality information on Hawke’s Bay lakes go to the website LAWA.  

Lake Monitoring

Hawke's Bay Regional Council monitors water quality and general health of 8 lakes in the region (from north – south):

  • Waikareiti
  • Waikaremoana – live data buoy
  • Kaweka Lakes (two)
  • Opouahi
  • Tūtira –live data buoy - see below
  • Waikopiro
  • Oingo
  • Runanga

Water quality monitoring buoy at Tutira:

HBRC and NIWA have a monitoring buoy on the main lake above one of the deeper holes (42m) for a long term study of the lake. The buoy measures dissolved oxygen, chlorophyll, water temperature and turbidity.

The data is automatically updated to this website and you can check it 

We also have a webcam at Lake Tūtira- so if you want to see how the weather's looking or what the lake is doing check that out here​.

Other lakes that HBRC does not monitor include Horseshoe, Whatuma and Lopez.

We also do investigate habitats and ecology of lakes for specific biodiversity projects.

Lake Tūtira investigations

Lake Tūtira has had water quality issues for several decades. Despite more than 30 years of works to improve water quality, the lake continues to have frequent algal blooms which limits swimming and other recreation. 

Starting in 2015 HBRC has been developing a computer model of the Tūtira – Waikopiro catchment to help understand how the lake works and improve water quality. Initial findings are that the lake water ‘flips’ in certain conditions, when cooler water from the lake bed rises bringing nutrients – algae food! – with it. When that happens algal blooms are likely.

The lake bed of Tūtira is also an amazing resource for geologists studying the history of New Zealand.  Core samples show evidence of successive earthquakes and the Taupō eruptions.

If you are interested in finding more information about Tūtira, HBRC has published a book 'Tūtira, a Brief History' - available from HBRC for $20.
