This means there are no longer restrictions on recreational activities and water sourced from this site is now suitable for stock and domestic uses.
However, water users should continue to monitor for signs of blue-green algae.
Algal numbers can change dramatically with changes in conditions, so water users should avoid water which is discoloured or gives off an earthy or musty odour.
Blue-green algae occur naturally and can reproduce quickly in favourable conditions where there is still or slow-flowing water, abundant sunlight and sufficient levels of nutrients.
People who believe they may have been affected by blue-green algae are advised to seek medical advice.
