Sydney, Melbourne and Brisbane have seen water levels hit near-decade lows after a hot summer and dry autumn
Naaman Zhou The Guardian 6 May 19;
Sydney, Darwin, Brisbane and Melbourne are all facing the prospect of dams below 50% capacity after low rainfall and high temperatures across the country.
In Sydney, inflows are at their lowest since 1940. Greater Sydney’s 11 dams were at a combined 55% capacity on Sunday – compared to 73% at the same time last year.
Sydney activated its desalination plant in January, when dam levels dropped below 60%, but levels continue to drop 0.4% a week. Stricter water restrictions will come into effect if the level drops below 50%. The last time Sydney’s dam levels neared 50% was in 2011.
In the Northern Territory, the Darwin river dam received its lowest-ever rainfall in March, as the territory recorded its driest wet season in 27 years. On Sunday, Darwin’s dam was at 76% capacity, compared with 98% last year.
In Melbourne, dam levels were at 51% on Monday, compared with 59% last year and 61% the year before.
