Fishy rumours spark panic — but officials confirm no toxic threat at Harties

Hartbeespoort – Recent social media posts warned residents to “be vigilant of people selling fish on the road around Harties.” The alarming claim alleged that “deadly chemicals were released into the Hartbeespoort Dam,” killing fish that were then supposedly being sold by the roadside.

On 6 November 2025, Platinum Weekly received an official media statement from Magalies Water, confirming that the only verified fish kill incident took place on 18 October 2025 at the canal near Venice Village Estate. The affected fish were subsequently buried on unoccupied land after the incident drew public attention around 21 October.

A joint inspection and water sampling were conducted on 22 October by Magalies Water, the Department of Water and Sanitation (DWS), and the Madibeng Local Municipality. Tests revealed no visible signs or evidence of chemical pollution, and no abnormalities were detected in the water quality.

Magalies Water spokesperson David Magae explained that, because the incident was reported several days after it occurred, water conditions may have changed by the time samples were taken — making it difficult to determine the precise cause. He added that continued monitoring of raw water around the dam has shown no further abnormalities since.

Experts believe the fish deaths were likely caused by low oxygen levels, a result of dense water hyacinth and salvinia growth combined with high levels of pollutants entering the dam. Residents are urged to report any future fish kills immediately to Magalies Water or the Department of Water and Sanitation, including photos and precise location details, to assist with swift investigation.

For now, authorities confirm there is no evidence of toxic chemicals in the Hartbeespoort Dam.
