Swimming Locations

Council monitors the concentrations of indicator bacteria every week from the beginning of November until the end of March. The results of this monitoring are used to assign ‘Suitability for Recreation Grades’ (SFR Grades). The map below shows the SFR Grades for the sites currently monitored. Zooming into the map will also show the risk to your health based on the latest result as well as the most recently measured water temperature.

The risk of catching an infectious disease from swimming in clear, clean water is usually low. However, after rainfall contamination occurs through runoff into waterways and there is an increased chance that you may catch a gut, ear, skin or respiratory infection.

The Marlborough District Council and Nelson/Marlborough District Health Board Public Health Service advise that after rainfall, it is best not to swim in discoloured water, especially for at least the first 24 hours and preferably 36 hours to minimise the risk of exposure to harmful bacteria. Further reduce your risk by:

Avoiding areas where stormwater outlets discharge to watercourses

Avoiding areas with high runoff from intensive agriculture
