AS of Monday, Glenmaggie Weir was at 6.1 per cent capacity – the lowest it has been in 16 years.
While a seasonal drop in water levels is nothing unusual, the resevoir’s current level of 10,922.9 megalitres means the old Glenmaggie Creek bridge has been exposed – an extremely rare sight.
The last time water levels fell so low was on May 16, 2003, during the Millennium Drought, when they dropped as far as 8262.8ML.
In the past 12 months, water levels peaked at 156,859ML on October 26, but a dry summer meant a steady decline.
This time last year, the water level was at 31,164.2ML, while the seasonal 10 year average sees levels sitting at 71,843.3ML this time of year.
This week’s predicted rainfall could stagnate the falling levels, with 8.8 millimetres falling at Glenmaggie Creek over 24 hours to Monday morning, according to the Bureau of Meterology.
