The bar chart illustrates the levels of water in reservoirs of six Australian cities (Darwin, Sydney, Melbourne, Brisbane, Perth, and Canbera) in October 2009 and October 2010, measured in percent.
Overall, the water levels have grown over the year in the most cities, except for Darwin, where they dropped, and Brisbane, where they remained unchanged. By October 2010, Canberra is the city with the highest percentage of water stored, whereas Darwin has the lowest level.
Notably, in October 2009, Sydney and Canberra were leading cities with aproximately 75% of reservoirs filled with water. However, by October 2010, water levels in Sydney rose only up to roughly 80%, whereas in Canberra they peaked at nearly 100%.
Darwin, starting at 45% of water stored in October 2009, experienced a significant decline down to around 29% in October 2010, which is half less than in Perth’s reservoirs with a little over 60%, taking the third place in water levels after Canberra and Sydney.
