Introduction to Water Safety
Water Safety NZ has highlighted the importance of being aware of hidden hazards when swimming in rivers and lakes. According to the organization, rivers are the most dangerous swimming spots due to factors such as fast currents and cold water. To stay safe, it is crucial to never swim alone, check for safe entry and exit points, and keep a close eye on children. Additionally, it is essential to ensure that the water is safe from health risks such as cyanobacteria or E. coli. The regional council tests over 92 popular swimming sites for these bacteria and shares the results with the Bay of Plenty and Lakes Public Health Service, which decides whether health warnings should be issued.
Health Warnings and Water Quality
Permanent health warnings are currently in place at several streams and lakes, including Utuhina Stream, Ngongotahā Stream, Uretara Stream, Kopurererua Stream, and Kaiate Falls. Meanwhile, Lake Ōkaro is under a temporary health warning due to a change in water quality. The regional council encourages people to check water safety levels before heading out, as it only takes a minute and could save them from an unpleasant or unsafe swimming experience. Water quality statuses are available at the Land Air Water Aotearoa website. The regional council also advises that heavy rain can further compromise water safety by washing contaminants from urban and rural land into waterways, and it is recommended to avoid swimming for two to three days after prolonged or heavy rain.
Cyanobacteria and Algal Blooms
The regional council notes that not all cyanobacteria produce harmful toxins, so a green lake or algal bloom does not automatically mean danger. However, if signs of a bloom are present and there is no warning, it is best to play it safe, especially if you have allergies or are immune-compromised. New signs have been installed to warn lake users about the risk of toxic algal blooms. The regional council is working alongside Te Arawa Lakes Trust and Rotorua Lakes Council to help improve the area’s lakes by promoting sustainable land use, reducing nutrients entering waterways, and protecting native plants and animals.
Summer Safety Reminders
As summer approaches, other lake users are being reminded to take care. Harbourmaster patrols began in October, focusing on lifejackets, safe speeds, and the "three to ski" rule for towing. Kayakers, stand-up paddleboarders, and users of waka or dinghies are encouraged to carry at least two forms of communication, check conditions before heading out, and let someone know their plans. Not wearing a lifejacket can result in a $200 fine. The regional council emphasizes that a little preparation goes a long way to keeping yourself and your family safe, as the lakes can be unpredictable.
Conclusion and Final Thoughts
In conclusion, it is essential to be aware of the potential hazards when swimming in rivers and lakes. By taking simple precautions such as checking for safe entry and exit points, keeping a close eye on children, and avoiding swimming after heavy rain, individuals can minimize their risk of injury or illness. The regional council’s efforts to test water quality and issue health warnings are crucial in keeping the community safe. By working together, we can enjoy the beautiful lakes and rivers while minimizing the risks associated with them. As the regional council notes, "our lakes are beautiful and provide amazing summer recreation, but they can also be unpredictable." By being aware of the potential hazards and taking necessary precautions, we can have a safe and enjoyable summer.
