In December 2016, the Menindee Lakes of New South Wales were nearly brimming
with water. More than two years later, these Australian lakes are almost desiccated.
These satellite images show the dwindling water levels of the Menindee Lakes, a
chain of freshwater lakes located 110 kilometers (70 miles) southeast of Broken Hill.
The shallow natural depressions were developed into water storage by the Austra-
lian government to manage river flows. The images were acquired by the Operational
Land Imager on Landsat 8 on January 27, 2017 (cover image), February 15, 2018, and
February 2, 2019.
Water levels often fluctuate as the basins collect precipitation or flood water. Evapora-
tion accounts for about 400 gigalitres of water loss from the lakes every year. Other times
the water is released into the nearby Darling River by the New South Wales government.
During drought, when less water is coming into the lakes, the basins tend to be drier.
Lake Menindee is the largest of the lakes. But river managers have been keeping
as much water as possible upstream in Lake Wetherell and Lake Panamaroo, which
supply water to Broken Hill and local communities.
Recent years have brought exceptional drought to the area. New South Wales has
faced extremely hot temperatures and low precipitation, causing one of its worst
droughts on record.
The Lower-Darling River has been experiencing “extreme low inflows” of water from
the Menindee Lakes since August 2018. As of February 18, 2019, the Lower-Darling’s
storage level was 1 percent. Water has stopped flowing in parts of the river.
