River Flow Changes
The viability of the floods plains relies of regular flood events that deposit soil and other water borne nutrients onto the plain.
The Googong Dam was constructed in 1979 on the Queanbeyan River at a point about 5 km above Queanbeyan. This structure regulates river flows below the junction of the Queanbeyan and Molonglo River. The lower Molonglo River experienced its last major flooding event in 1971.

Famous quotes containing the words river and/or flow:
“The name of the town isn’t important. It’s the one that’s just twenty-eight minutes from the big city. Twenty-three if you catch the morning express. It’s on a river and it’s got houses and stores and churches. And a main street. Nothing fancy like Broadway or Market, just plain Broadway. Drug, dry good, shoes. Those horrible little chain stores that breed like rabbits.”
—Joseph L. Mankiewicz (1909–1993)
“And if blood of Martyrs is to flow on the steps
We must first build the steps;
And if the Temple is to be cast down
We must first build the Temple.”
—T.S. (Thomas Stearns)
