SunWater is undertaking a dam spillway capacity upgrade program to ensure the continued safety of the dam. [8] During the 1995 drought dam levels declined to a low of 1% total capacity. [ 9 ] The dam reached 100% capacity due to rainfall associated with the 2010–2011 Queensland floods , with water flowing over the spillway for the first time ...
On 11 January 2011, Wivenhoe Dam reached its highest level ever, 191% of normal water supply storage capacity, as it held back floodwater. [16] Because it is an embankment dam, it was not designed to spill over its crest or overtop and there is a risk that if waters spilled over the crest, this could erode the dam wall and potentially cause the ...
The North Pine Dam was designed with little flood mitigation capacity in mind, being designed only for water storage. As such, during flood seasons the location of the dam spillway causes the flooding and closure of Youngs Crossing Road. [3] Flood conditions last affected the dam catchment in October 2010, and prior to that 1991, 1989 and 2000 ...

[1] [3] The impounded reservoir is called ...
Testing of the pipeline to Wivenhoe Dam has been conducted, however in November 2008, Premier Anna Bligh declared that recycled water will not enter the dam unless levels drop to below 40%. [5] Initially, the three power stations were the main customers of the recycled water, consuming 112 megalitres (25 × 10 ^ 6 imp gal; 30 × 10 ^ 6 US gal ...
