Freshwater and Estuaries

Robust science is critical in the sustainable management of our precious freshwater resources and estuarine environments.

The National Centre for Freshwater and Estuaries provides public information on river, lake, and groundwater conditions across New Zealand including water quantity and quality. It also acts as a distribution point for new technology and management tools for water-related issues.
