About this report

A long-term monitoring programme of Lake Taupo’s water quality was commissioned by Waikato Regional Council in October 1994 in the expectation that the trophic state of the lake would change to reflect changes in land use within the lake's catchment.

This programme is conducted by NIWA, with field assistance from the Department of Internal Affairs, Taupo Harbourmaster’s Office.

This report presents data from the routine mid-lake monitoring station from July 2015 to June 2016.
