The safety of water for swimming is determined by measuring ‘faecal indicator bacteria’ (E. coli) which indicates the likely levels ofs in the water. Monitoring is conducted on a weekly basis over the summer months (December to March).
It is generally safe to swim at this site during dry weather. However the site is known to be affected by faecal contamination from urbanfollowing heavy or prolonged rainfall. We therefore advise people not to swim for at least two days after heavy rain.
The site can also be affected by (also known as 'toxic algae') blooms during the summer. For the latest toxic algae warnings and other water quality information, please go to the GWRC website, or check out the latest recreational water quality reports.
