<p>This indicator reports on six measures of lake water quality based on spatially modelled data for:</p>
<ul>
<li>chlorophyll-a </li>
<li>total nitrogen </li>
<li>ammoniacal nitrogen </li>
<li>total phosphorus </li>
<li>water clarity </li>
<li>trophic level index (TLI3).</li>
</ul>
<p></p>
<p>For these measures we report on:</p>
<ul>
<li>modelled median values for the period 2013–17 </li>
<li>for selected measures, how these values compare to the <a href="https://www.mfe.govt.nz/publications/fresh-water/national-policy-statement-freshwater-management-2014-amended-2017">National Objectives Framework</a> (NOF) bands related to ecosystem health (MfE, 2017).</li>
</ul>
<p></p>
<p>This indicator includes spatial predictions for 3,802 of 3,820 lakes in New Zealand (majority of New Zealand lakes that are larger than 1 hectare), based on measurements at 61–104 lake sites (the number of sites differs by measure).</p>
