THE Hinze Dam has been closed to boaties, anglers and other recreational users after abnormal levels of the potentially deadly E. coli bacteria were found in the water.

Water testing by SEQ Water this week confirmed higher than normal levels of the bacteria in the untreated dam water.

Recreational access was closed yesterday as a precaution until further tests were carried out, with all water-based activities suspended.

E. coli is a bacterium with hundreds of different strains. It can be deadly to humans in high doses, while lower amounts may cause gastroenteritis-like symptoms such as abdominal cramping and diarrhoea.

SEQ Water CEO Peter Borrows stressed it did not affect the quality of drinking water on the Gold Coast.

He said that Queensland Health had advised SEQ Water to take a precautionary approach pending the outcome of a further series of water quality tests.

"E. coli occurs naturally in dams and weirs and is just a normal part of managing open water storage systems," he said.

The gate to the ramp eastern arm was open yesterday with no warning signs up , people were out canoeing. The condition of the launching area I would say is difficult for 2 wheel drive. Water level is between 2.5 - 3 mts beyond end of concrete ramp.
