Our Region is home to many popular swimming spots which provide fantastic places to cool off when conditions are right. At the same time it's important to remain mindful of risks presented by swimming in a natural environment and keep an eye out for rips at beaches and sunken logs, rocks and river bank trees in rivers that could present a hazard.
The links to information on the freshwater and coastal swim spot pages below is the most reliable source of day to day guidance on the potential health-risks to people and animals from using our waterways. The assessments are based on the density of health-risk indicator bacteria and cyanobacteria (blue-green algae) growths sometimes observed in some rivers and popular coastal lakes. The advice is based on NZ guidelines for these parameters.
Horizons Regional Council reports on water quality at popular swimming spots in the Region between 1 November and 30 April each summer season.
The information is as up-to-date as possible, but we cannot predict changes in river water quality due to weather conditions or one-off pollution incidents since our last observation. In reality you are the best judge of the suitability of a swim spot when using the following rule of thumb:
If you wish to view the long-term grading of sites in New Zealand you can find it at the LAWA website. LAWA provides water quality information and comparisons on monitored sites from across New Zealand including the Horizons Region . Gradings are based on the Microbiological Water Quality Guidelines for Marine and Freshwater Recreational Areas (2003). The gradings are based on the results of long-term monitoring and a risk assessment of activities in the catchment. They are most suited to state of the environment reporting. They are less suited for day to day guidance and do not consider the potential health-risk to people and animals from cyanobacteria proliferations.
