Overwhelmingly, the changes occurred to support agricultural production.Food and fibre production has driven the vast majority of land clearing decisions, and the regulation and diversion of rivers.Where land clearing has exacerbated salinity problems, the rivers draining these areas have experienced increased salt levels.

Rivers have also been dammed for domestic and industrial supply, but this component comprises a very small part of the big picture.

By far the largest demand on Australia’s water resources – 75% of all surface water use – comes from irrigated agriculture.

Why do we need healthy ecosystems for our water supply?

Before the Canberra bushfires, Canberra’s water was primarily sourced from the Cotter Catchment, located in Namadgi National Park.

This higher level of water treatment will be required to treat Cotter water until the vegetation recovers.

The episodic and unpredictable nature of natural flows were not conducive to the water needs of European agriculture, domestic and industrial uses.Nevertheless, domestic and industrial water uses are also important.Most capital cities and many towns are now approaching the limits of their local water supplies, and are actively enforcing water restrictions.Nicky Grigg Contents Water flowing through Australian history Land clearing can alter rivers irreversibly Interlinked water stories: cities and agriculture Water Reform in Australia Water in Australia is a contentious topic; mentioning it in any social or professional context invariable uncovers a rich array of opinions, usually expressed with plenty of emotion.Water flowing through Australian history Water has been at the centre of nation-building projects such as the massive Snowy Mountains Hydroelectric Scheme (construction dates from 19), the Ord River Irrigation Scheme (constructed from 1963 to 1972) and C. O’Conner’s Coolgardie Goldfields Water Scheme (constructed from 1989 to 1903) with its famous pipeline carrying water from the hills near Perth to Kalgoorlie.Fertilisers and soil contain nutrients needed for plant growth, but in waterways the nutrients fuel algal problems in inland waters.If rivers deliver these nutrients to coastal regions they pose a threat to sensitive and highly valuable coastal ecosystems such as the Great Barrier Reef.Land clearing can alter rivers irreversibly Expansion of European settlement in Australia marked the beginning of widespread land clearing, construction of dams and weirs, and the diversion of water for agricultural, domestic and industrial purposes.These have triggered changes to the quantity of water available in different locations and the speed with which water moves through the landscape. For example, the Western Australian wheatbelt has had approximately 85% of its native vegetation cleared for agriculture. Rainfall landing on cleared land is more likely to move rapidly across the land surface, eroding valuable topsoil in its path and eventually creating erosion gullies.An attempt to dam Tasmania’s Franklin River (Gordon-below-Franklin Dam project, proposed in 1978) sparked one of the most passionate and high-profile environmental movements yet seen in this country and contributed to the change of government in the 1983 Federal election.A proposed canal to transport water from the Fitzroy River in the Kimberly to Perth played a prominent role in the 2005 Western Australian State election.
