About this report
This report was commissioned by the Technical Leaders Group for the Healthy Rivers Wai Ora Project Report No. HR/TLG/2015-2016/4.2
The Healthy Rivers: Plan for Change/Wai Ora He Rautaki Whakapaipai (HRWO) project will establish targets and limits for nutrients (nitrogen and phosphorus), sediment, and E. coli in water bodies across the Waikato and Waipa catchments. As part of the process of establishing targets and limits, the Collaborative Stakeholder Group (CSG) asked for a technical assessment of four initial scenarios. These initial scenarios were associated with a diverse set of goals for water-quality improvement, and were purposely developed by the CSG to help them to explore a wide range of ‘possible futures’ and timeframes to achieve them. Based on their analysis of a modelling assessment provided for this initial set of scenarios, the CSG have recently provided an alternative set of scenarios to explore.
