About this report

This report was commissioned by the Technical Leaders Group for the Healthy Rivers Wai Ora Project Report No. HR/TLG/2015-2016/1.5A

A greater understanding of water resources within the Waipa River Catchment (Waipa Catchment) is required and WRC has commissioned GNS Science (GNS) to carry out a short term field investigation in the Waipa Catchment, aiming to improve the bank of knowledge underlying Healthy Rivers policy options
The primary reason for undertaking these initiatives are concerns regarding the potential for water quality deterioration due to land use changes such as intensification and deforestation.
