A year ago intelligent people were speculating that the Googong Dam would never fill again.
Today Simon Corbell has officially opened the upgraded spillway, completed just in time to handle major waterfall event you can see above.
“The works on Googong Dam spillway have been comprehensive and involved repairing eroded sections and extending the spillway walls to improve the flooding capacity of the dam,” he said.
The Googong Dam spillway upgrade meets the Australian National Committee on Large Dams (ANCOLD) requirements to pass extreme floods.
“The Googong Dam spillway is now able to safely pass 10,500 cubic meters of water per second, which is approximately four times the normal flow over Niagara Falls and a 1 in a million event,” Mr Corbell said.
“On Friday 3rd December during the extraordinary rainfall event that resulted in the Queanbeyan floods, up to 700 cubic meters of water per second safely flowed over the spillway.”
