The bar chart gives information about the levels of six water reservoirs in Australia in October 2009 and October 2010. Overall, the percentage of water levels rose across all reservoirs over the period, except for Darwin and Brisbane, with the former seeing a decline and the latter remaining unchanged in both years. It becomes evident that Sydney and Canberra reservoirs had the highest figure, while Melbourne and Darwin recorded the smallest share.
In more detail, the figure for Canberra stood at around 75% in October 2009, followed by a significant growth in the next year. The proportion of Sydney reservoir was at 75% in 2009, same as Canberra’s initial figure. Then it experienced a marked rise to 80% in 2010. Similarly, the share of Perth also followed an upward trend from 40% to 60% between 2009 and 2010. Likewise, the water levels in Melbourne reservoir contributed 25% in the initial year, after which this figure increased significantly, reaching 38% by the final year.
In contrast, the percentage of water levels in Darwin reservoir exhibited a noticeable decrease, from about 45% in 2009 to approximately 38% in 2010. Brisbane accounted for roughly 55% and this figure remained intact in the subsequent year.
