Biosecurity considerations ahead of the Kai Iwi Lakes Triathlon
Follow new Check, Clean, Dry rules to protect the lakes at Taharoa Domain
Exotic freshwater clams (Corbicula) can harm everything we love about the water.
Before you arrive at Taharoa Domain, play your part in protecting the lakes from exotic freshwater clams. Follow new Check, Clean, Dry rules for all watercraft, gear, or clothing at other lakes or rivers, especially the Waikato River. Biosecurity spot checks are being done during the summer break.
Te Roroa iwi, Te Kuihi hapū, Kaipara District council and the Northland Regional Council ask that you please check, clean and dry all swimming, kayaking or support boat equipment prior to training and competing in Lake Taharoa. This is to protect the water quality of Lake Taharoa and Te Taitokerau from invasive freshwater threats (such as Freshwater gold clam – Corbicula fluminea, hornwort and other invasive species).
How to CCD (Check, Clean, Dry)
Check – Check your wetsuit, swim equipment and kayaks, remove any visible matter such as weed or algae.
Clean – Your wetsuit, swim equipment and kayaks. Hose your wetsuit, swim equipment and kayaks inside and out onto grass area, not a stormwater drain. Use one of the following treatments. Hot water between 50 - 54 °C (hot household tap-water) for at least 5 minutes, or Above 45°C for at least 20 minutes. Or freeze overnight.
Dry – Allow gear to dry to touch, inside and out, then leave it to dry for at least 48 hours (2 days) before using again.
Watercraft: Dry areas inside the watercraft where water has pooled, for example with an old towel, and then leave the craft to dry for at least 48 hours (2 days). The hull of a watercraft will dry when towed. These new Check, Clean, Dry steps will also help stop the spread of other freshwater pest species.
