Adapted by Ministry for the Environment and Statistics New Zealand to provide for environmental reporting transparency. Dataset used to develop the "River water quality: clarity and turbidity" indicator (available at https://www.stats.govt.nz/indicators/river-water-quality-clarity-and-turbidity).
This dataset contains two parameters of water quality based on measurements made at monitored river sites:
Clarity and turbidity in river waters is one of five parameters that provide an overview of New Zealand’s river water quality and how it is changing over time.
This dataset includes:
clarity and turbidity as measured median values at monitored sites for New Zealand’s river length for the period 2016–2020
how these values compare to the default guideline values in the Australian and New Zealand guidelines for fresh and marine water quality (ANZG, 2018), which indicates the risk of environmental impairment
measured visual clarity median values compared with the National Objectives Framework (NOF) bands related to ecosystem health (MfE, 2020)
More information on this dataset and how it relates to our environmental reporting indicators and topics can be found in the attached data quality pdf.
