IN an effort to establish how much water is available between Gingin and Moora for agriculture and industry up to 21 new exploration bores will be drilled during the next eight months.

As part of a $5.1 million investigation looking at how to address water needs for horticulture and the environment the bores will be constructed across the Dandaragan plateau to provide new data on the quality, quantity and flow direction of groundwater in the area.

The study is also investigating the management of water use around the Gingin Brook, which relies on groundwater to support its flow and has experienced up to a 40 per cent decline in streamflow since 2010.

The investigation by the Department of Water and Environmental Regulation (DWER) will also study how to keep water sources sustainable under climate change.

The information will help the department establish if there is more water available for agriculture and industry and where to access it.

The drilling program follows a 7500sqkm aerial electromagnetic survey last year and is part of the department’s state groundwater investigation program.

Water Minister Dave Kelly said the area was a high value horticultural area with a big number of groundwater and surface water licences.

“Its groundwater dependent brooks and streams also support some of the most diverse populations of native fish in the south-west of the state,’’ he said.

“This work will give us the right data at a local scale to continue to manage water for irrigation as well as the environment.

“It will also identify potential areas where more water can be taken from, or where increased use is sustainable, and complements previous groundwater investigations in the Dinner Hill and Gingin areas.”
