As we enter a long hot summer, with temperatures soaring to 45, the Darling River at Bourke continues to drop to unprecedented levels.

And former NSW Water Licensing Officer Allan Amos says that with no rain in sight, the town of Bourke could run out of water.
“No-one thinks about the possibility” says Allan “but unless we get rain soon the river could drop to lows that we haven’t seen for many years”.
Allan, who was based in Bourke in various Water Officer positions for 32 years, said the river level at Bourke is currently just over 3 metres – about 89 centimetres below the weir crest – and is continuing to fall at about 1 centimetre per day.
“In my 44 years in Bourke, the lowest river level was 2.81 metres on 3 January 1995.
