Freshwater

Understanding and supporting the migration of fish through New Zealand's freshwater habitats

A team of NIWA freshwater ecologists are researching the use of biodegradable plant mats to help reintroduce native aquatic plants to degraded freshwater lakes in Aotearoa-New Zealand.

NIWA is developing a national river flow forecasting tool for New Zealand that aims to support and strengthen our planning for and response to extreme rainfall events.

We offer a range of ecological monitoring tools.

This project aims to increase our knowledge of aquatic ecosystems and their restoration, and apply this to degraded streams, rivers, lakes and estuaries.
