Lake Rotorua

Supporting information

Since the proposed Lake Rotorua Nutrient Rules have been notified new research and supporting information has been made available:



OVERSEER® Nutrient Budgets information base for the Rotorua catchment

The purpose of this report is to compare measured N leaching values against OVERSEER® nutrient budget (hereafter referred to as OVERSEER) modelled N leaching values for the same farm system. This report will help with understanding how OVERSEER modelled values reflect against measured trial N leaching data in the Rotorua catchment.

Anthropogenic Phosphorus Loads to Lake Rotorua

This report was commissioned by the Bay of Plenty Regional Council to quantify sources of anthropogenic (i.e., associated with human activity) phosphorus in the catchment, so that these sources can be managed with the aim of reducing phytoplankton biomass in Lake Rotorua.
Update of the 2014 NDA Impact Analysis An update of the original report on the impact that NDAs may have on farm profitability.
