In a post on social media the council said water quality samples "just tested" showed high levels of bacteria in the creek.
"People are advised not to swim or use the water for other recreation until further notice. A warning sign is in place."
Land, Air, Water Aotearoa (Lawa) said the water was last sampled on December 23.
It said the creek could be prone to high bacteria levels from sources upstream.
"After calm weather, it is generally suitable for swimming, but after heavy rainfall this site can suffer from higher bacteria concentrations. We recommend you stay out of the water for 48 hours after heavy rain."
The ORC earlier this week issued toxic algae alerts, advising people to stay out of three southern waterways.
Lake Waihola, Aronui Dam and the Cardrona River each had alerts issued on Tuesday.
"Observations show toxic algae (cyanobacteria) blooms at present in the Cardrona River.
"Such blooms are currently found in the lower reaches (below State Highway 6), but likely to be found further up.
"We advise avoiding contact with the water at Cardrona River and other sites with toxic algae," the council said on social media.
The same alerts were issued separately for the other waterbodies.
In humans, exposure could lead to rashes, nausea, upset stomachs and tingling and numbness around the mouth or tips of fingers.
In animals it could lead to lethargy, muscle tremors, fast breathing, twitching, paralysis, or convulsions.
"If you or your pet experience health symptoms, visit a doctor or vet immediately," the council said.
