The New South Wales government has announced plans to build an A$342M (US$261.5M) dam in the Hunter Valley to help boost water supplies in the Australian state.

According to NSW Premier Morris Iemma, the dam will ‘drought-proof’ the areas of Newcastle and the Central Coast for the next 60 years, and will form part of a new water grid planned for the region. It will be built at Tillegra, north of Dungog, on the Williams river.

Construction of the dam – which will more than double the Hunter Valley’s current water holding capacity – is expected to start in 2008.

According to local media, the latest figures show that the state is 93.6% drought declared – up 4% on last month.
