<br /><strong>Updated with new data on 14 Apr 2020</strong><br />
<p><strong>16 April 2020: Subsequent to publication in April 2019 we discovered two small errors with this dataset. These included:</strong></p>
<ul>
<li><strong>Errors in the coordinates of some sites and their associated metadata (such as landcover and elevation).</strong> </li>
<li><strong>Errors in our calculation of dominant landcover.</strong></li>
</ul>
<p><strong>In addition, flow data from TopNet has also been updated.</strong></p>
<p><strong>These changes have a minor impact on overall results. These changes have have been corrected, and are republished here, as part of the Our freshwater 2020 release.</strong></p>

<p>This dataset contains ten parameters of water quality based on measurements made at monitored river sites:</p>
<ul>
<li>Nitrate-nitrogen </li>
<li>Ammoniacal nitrogen </li>
<li>Ammoniacal nitrogen (adjusted) </li>
<li>Total nitrogen </li>
<li>Total phosphorus </li>
<li>Dissolved reactive phosphorus </li>
<li>Water clarity </li>
<li>Turbidity </li>
<li>Escherichia coli </li>
<li>Macroinvertebrate community index</li>
</ul>
<p>This dataset includes:</p>
<ul>
<li>Median values for the period 2013 to 2017 </li>
<li>for selected indicators, how these values compare to the National Objectives Framework (NOF) (MfE, 2017) bands related to ecosystem health and human health for recreation, and to expected concentrations in natural conditions, as shown by the default guideline values in the Australian and New Zealand guidelines for fresh and marine water quality (ANZG, 2018)</li>
</ul>
<p>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.</p>

<p>This dataset measures how water quality in New Zealand’s rivers is changing over time. It contains nine parameters of water quality based on measurements made at monitored river sites in years 1990-2017:</p>
<ul>
<li>Nitrate-nitrogen </li>
<li>Ammoniacal nitrogen </li>
<li>Total nitrogen </li>
<li>Total phosphorus </li>
<li>Dissolved reactive phosphorus </li>
