The bar chart illustrates water reservoirs in six Australian cities—Darwin, Sydney, Melbourne, Brisbane, Perth, and Canberra—for 2009 and 2010, measured as a percentage of maximum capacity.
Overall, Sydney and Canberra were two cities with the largest water supplies in both given years, with their reservoirs filled with more water over the year. In fact, Canberra was filled with maximum water in October. While Melbourne and Perth grow substantially, the reverse was observed in Darwin city, where its water level decreased by double. Brisbane, however, was one city that stayed unchanged over the past two years.
The water level in the Sydney reservoir amounted to about 79 percent in 2009, slightly increasing to 80 percent in the year 2010. Canberra’s water supplies also increased but more significantly from an initial 78 percent to approximately 99 percent in 2009 and 2010, respectively.the rise of the water reservoir was observed In other parts of Australia. In both Melbourne and Perth, the amount of water supply had soared with significant change, the former being much lower in 2009 with above 20 percent to under 40 percent, the latter, however, figuratively doubled, starting from 21 and ending with 40 percent in 2009 and 2010.
Darwin, contrastingly with the above-mentioned cities, decreased the amount of water reservoir at 42 percent in 2009, halved by declining to 22 percent a year later. Brisbane Water Reservoir, on the other hand, had the same amount of water in both given years, at only 55 percent
