The Murray-Darling Basin is Australia's most important farming area. Water from the Snowy Scheme is used to irrigate crops of wheat, cotton, rice, fruit and vegetables, as wells as pastures for sheep and cattle to graze on. Products from this area, such as wool, dairy products, wine and oil seed, are sold in Australia and overseas. This is vital to Australia's economy. Along the way, water evaporates.
Evaporation is when water heats up and becomes vapour in the air.
This vapour collects in clouds and the water cycle starts all over again. So water is renewable. Lake Eucumbene is the heart of the Snowy Mountains Hydro-electric Scheme network.
