The bar chart gives information about the levels of water in reservoirs of six Australian cities in October 2009 and October 2010.
The bar graph compares the proportion of water levels in six different reservoirs in Australia between October 2009 and October 2010. Overall, while the percentage of water levels in the reservoirs of Sydney, Melbourne, Perth, and Canberra increased, the opposite trend was observed in Darwin and Brisbane, with the latter remaining relatively unchanged over the period. Notably, the figures for Sydney and Canberra were higher than those of the other cities in both years, whereas Melbourne had the lowest levels throughout the period.
Starting at 74%, the water level in Canberra rose significantly to just under 100% in October 2010, making it the city with the highest water levels among the six by the end of the period. Similarly, Sydney also showed an upward trend, beginning with almost the same percentage as Canberra (74%) and increasing slightly to just over 80% in the final year, ranking as the second highest figure. Perth and Melbourne also experienced growth. The water levels in these cities were 40% and 25%, respectively, in the first year, but they rose sharply to 61% and just under 40% by October 2010, with Melbourne’s final figure matching Perth’s initial water level.
In contrast, Darwin experienced a noticeable decline. Starting at 45% in October 2009, its water levels dropped to 38% by October 2010. Meanwhile, Brisbane’s water levels remained stable at 55% throughout the period.
