The Isaac towns with less than 12 months of water
ISAAC Regional Council's water woes are showing no sign of letting up after it was forced to cancel level 2 water restrictions for Clermont on Thursday after being announced on September 4.
Water data provided to the Department of Natural Resources, Mines and Energy also indicated Isaac towns of Glenden, St Lawrence, Carmila, Dysart and Middlemount had less than 12 months water supply remaining.
In a post on its Facebook page on Thursday, the council said it had been made aware of a "serious issue" relating to the water restrictions, which prompted the council to launch a full investigation.
The council's chief executive Gary Stevenson said the level 2 water restrictions for Clermont should not have been imposed.
"The restrictions were considered by council officers to be justified based on automatic sensor readings of the levels at Theresa Creek Dam on the morning of Monday, September 4," Mr Stevenson said.
"The readings had not been validated by visual inspection which should have been done."
The sensor was later confirmed to be faulty late on Friday, September 6.
"Council officers failed to correct the situation and arrange for withdrawal of the restrictions," Mr Stevenson said.
A DNRME spokesman said the council in June advised it planned to implement water restrictions if required.
"Miriam Vale, in Gladstone Regional Council's area, was the only other Central Queensland town that reported water supply issues and council also had plans in place to address this," the spokesman said.
A total of 90.3 per cent of the Isaac region was drought declared as of September 1, 2019.
Earlier this week, mining company Anglo American also issued a letter to Middlemount residents advising the Bundoora Dam would be closed from Thursday, September 12 due to "dangerous" levels of blue-green algae and low water levels.
"Low water levels resulting from extended drought conditions mean the dam is not safe for recreational watercraft use, and current levels of blue-green algae in the water are not at an acceptable level to allow public access," an Anglo American spokeswoman said.
Bundoora Dam is privately-owned by Anglo American and is located on its mining lease.
The dam and associated amenities are maintained by Anglo American and made available for public recreational use when conditions are safe.
The dam is not connected to other water sources, including potable water supplies.
The council said there were no issues with any of IRC's town drinking water supplies within the Isaac region.
In November last year, Isaac Regional Council was forced to pay back Clermont residents after water quality deteriorated, causing it to discolour for several days.
