<br /><strong>Updated with new data on 27 Jun 2018</strong><br />
<p>Water quality for swimming categories for lakes with perimeters over 1.5 km. This dataset was used to compose the current state for water quality for swimming. </p>
<p>Note this data is under review and will be updated in due course. This information is based on modelled and measured data using the approach outlined at<br>
