The plan announced a hand back of up to 3,200
gigalitres of water to the environment in annual average flows, achieving only 65 per cent of the environmental flow targets which define a healthy river system.
Between 1909 and 1948, the average annual rainfall across this area was 780 millimetres, with calculated dam inflows of 892
gigalitres. A climate shift then appears to have occurred between 1949 and 1990, when annual rainfall leapt to 907 millimetres and inflows to just over 2,000
gigalitres.
The Murray Darling Basin Commission expects water efficiency measures and engineering improvements to save about 300
gigalitres by mid-2009.
These purchases bring the total groundwater recovered to 18.65
gigalitres (in long term average annual yield terms), or almost half the target for the Queensland Upper Condamine Alluvium.
It is the largest dam in the River Murray system and can store nearly 4,000
gigalitres, which when full holds more than 40% of the River Murray system's total storage capacity.
Even after the release, as of Monday morning, the dam was still at 229 percent capacity, holding about 532,000
gigalitres of water, or roughly as much as Sydney Harbour.
The decision to build the 1 123
gigalitres of storage high in the Baw Baw Ranges was triggered by severe water restrictions in Melbourne during the 1967 drought (see figure 4).
Eighty-eight
gigalitres (GL) of water were delivered to the main lakes between 19 May and 11 September 2014, and 16 GL were delivered to Lake Kramen between 7 September 2014 and 18 January 2015.
In the water year 2004-05, it accounted for 12,191
gigalitres or 65 percent of total water consumption (ABS 2006) and in 2008-09, despite the long-lasting drought, still for more than half of the water use (7,589
gigalitres) (ABS 2010).
I am pleased to also share with you our satisfaction in seeing federal parliament finally LEGISLATE 3200
GIGALITRES of environmental water plus extra money to improve the positive impact of the flows for the Murray-Darling Basin.
Canberra wants water usage cuts of 2,750
gigalitres a year in the vast Murray-Darling Basin in Australia s east which produces more than one-third of the country s food supply and has been over exploited for years.
To further prove the effectiveness of his company's technology, Miles said, "In 2010, during the Holy Month of Ramandan, we delivered 4
gigalitres of rain in Qatar which is equal to the volume of water supplied in the country for 10 days.
