Lakes

Latest news

Visitors to NIWA’s stand at this year’s Fieldays are invited to go diving into the Rotorua lakes—without having to get wet.
NIWA researchers are out on Lake Whakatipu for the next week mapping the lake floor for the first time.
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.

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.

Diving deep to check up on our lakes

NIWA scientists jump overboard to check out the health the Rotorua Te Arawa lakes. The work is part of NIWA's national LakeSPI programme—an ecological health check for lakes throughout New Zealand.

Modelling future water quality in Lake Benmore

The lakes of the Upper Waitaki Basin – Lakes Benmore, Aviemore, and Waitaki – are highly valued for their clean water. But land use is intensifying in the lakes’ catchments, and concerns for future water quality are growing. NIWA scientists have worked alongside Waikato University scientists to model  the potential impact of intensifying land use on water quality in Lake Benmore, to help Environment Canterbury with its regional planning.

World first in bio-crude oil research

“The reality is that no one in the world has done anything on this scale. Our trial aims to show that this complete process can be cost-effective and efficient”, says NIWA scientist Dr Rupert Craggs. Twelve years of research by NIWA’s Aquatic Pollution Group has culminated in the world’s first large-scale trial of the production of algal bio-crude oil from wastewater.
