At about midday signage warning motorists of the croc sightings was placed on the road leading to the dam.

A decision is yet to be made on when the area will reopen.

Cloncurry water treatment plant manager Scott Cosgrove said the decision was made due to the aggressive behaviour the croc had displayed.

Mr Cosgrove said the crocodile ran aggressively towards the local ranger’s vehicle at the weekend.

He said the size of the croc was estimated at 4.5m yesterday based on tracks it left after spending the night laying at the riverbank.

“It’s a popular area for people to come and throw out a line so we didn’t want to take any chances,” he said.

It was yet to be determined whether the crocodile was a saltwater or freshwater, however representatives from Queensland Parks and Wildlife would arrive in the town in the coming days to track down the animal.

The crocodile was first spotted last week but has since been confirmed with sightings by local rangers and residents.

“We are thinking about using the local rangers to try and trap it,” Mr Cosgrove said.

“But obviously we will be taking our lead from the parks and wildlife guys.”

In a statement yesterday, Cloncurry Shire chief executive officer Craig Turnour said while total access to the dam had not been closed, he warned residents to take serious precautions for their safety if visiting the area. REPEATED sightings of an aggressive 4.5m crocodile at Chinaman Creek Dam near Cloncurry forced the shutdown of access to the waters yesterday.

At about midday signage warning motorists of the croc sightings was placed on the road leading to the dam.
