Murray Darling Basin

FINLEY, NSW - AUSTRALIA - FEBRUARY 20: Calves lap up milk left over from the morning milking at Giles and Annie Gay's dairy farm February 20, 2008 in Finley, New South Wales, Australia. The Gay's farm is on 0% water allocation and they are still trying to run their dairy farm. They have put their farm on the market but are unable to sell because there is no water. They have had their Jersey Milking cow line since 1929. The Murray-Darling Basin has been plagued with severe drought since the late 1990s and many growers and policy makers are being forced to work on implimenting more efficient irrigation systems.
