Cania Dam knocks record off charts
CANIA Dam was expected to spill for the first time in history last night with the water just 60cm from overflowing at 5pm.
Sunwater staff were checking the levels hourly and caretaker Brett Powter said the spill would be the first real test of the dam’s strength since it was completed in 1983.
“The highest it has ever been is 76% and it’s well above that now,” Mr Powter said.
“We expect it to be full by about 8 or 9pm.”
A Sunwater spokeswoman said Cania was at 94% capacity about 3pm with the water rising about 10cm an hour.
“If it were to overflow, this will be the first time since it was built, however this will depend on how much inflow it receives,” the spokeswoman said.
“The highest Cania has ever reached was 75.6% in February 1991 and the lowest was 3.3% in February 2003.
Thousands of mega litres of water have been breaching spillways of dams across the region with 695,500ML a day spilling from Paradise alone.
Paradise is sitting at 173% while Fred Haigh sits at 139% passing 53,000ML over the spillway each day.
Wuruma Dam, which breached its spillway for the first time in 40 years on Monday, is currently at 132% and passing around 67,000 ML a day over the spillway
