NIWA discusses, in depth, this year's most asked question—what is happening to our fresh waterways?
NIWA researchers have spent part of the last month keeping a close eye on the bottom of Lake Tekapo to find out what it looks like and what is going on below the lake bed.
A NIWA study has shown that environmental factors influence the level of mercury in fish and other organisms in lakes in New Zealand's North Island geothermal area

John Clayton, a principal scientist in the fields of aquatic biodiversity and biosecurity based at NIWA's Hamilton office, has won a 2011 Kudos award for his leading role in the development of LakeSPI  (Lake Submerged Plant Indicators). 

Our work

This research project aimed to understand the causes behind differences in mercury in trout and other organisms in the Bay of Plenty/Te Arawa lakes—in particular what features of each lake explain why mercury in trout is higher in some lakes than in other lakes.

NIWA recently hosted visitors from Northland to view cultivated plants from Lake Ōmāpere that are now ‘extinct in the wild’, and discussed plans for their reintroduction to the lake in the future. 

The ability to properly manage our freshwater resources requires a solid understanding of the flora and fauna which live in and interact with them.
This project aims to increase our knowledge of aquatic ecosystems and their restoration, and apply this to degraded streams, rivers, lakes and estuaries.
