Drought is an ongoing problem across Australia, and many of us like to know how well-stocked our local water suppliers are. Melbourne Water's iPhone app offers that information in an iPhone-friendly format, letting you track current dam levels and compare those levels to the same time a year ago.
The free app also includes rain catchment data and figures on weekly residential water use. While that's also information you could get from the Melbourne Water web site, anything that makes people more water-conscious is welcome.
