Abstract

The report provides information on:


1. Routine monthly monitoring of water quality at 12 sites:

  • Year 2020 summary data tabulated by parameter for each location and reported with the median of the previous 5 years.
  • Key parameter graphs showing the average water quality for 2020 at each location, compared to results of the previous 5 years.
  • Summary tables identifying the number of samples meeting ‘satisfactory’ and ‘excellent’ water quality standards and guidelines.
  • Raw data for 2020.


2. Additional information is provided in the appendices on:

  • Flow (Appendix I).
    • The effect of flow is important to assessing water quality and making comparisons between years. Appendix I provides information on annual median flow at some locations for the previous 10 years.
  • Continuous monitoring data via Datasonde (Appendix II).
    • Plots of the Hamilton and Tuakau deployments undertaken during 2020 showing the level of diurnal and seasonal variation of selected parameters.
  • Water quality criteria (Appendix III)
    • Identifying the water quality parameters, guidelines, standards, and analytical methods used in the Waikato River water quality monitoring programme.
