Unrestricted pumping ends for Gascoyne irrigators
Released 02 Jul 2015
A declaration allowing unrestricted pumping of water by licensed Carnarvon irrigators from the Riverbed Sands aquifer and lower Gascoyne River has ended.
Department of Water Mid West Gascoyne regional manager Darryl Abbott said late rains had allowed the extra unrestricted pumping for the month of June but despite continued river flows, restricted pumping had to be resumed due to water quality.
"Water quality measurement in the last few days was around 750 mg/L and increasing around 25mg/L a day," he said.
"We expect the readings to level off at around 900mg/L in about a week's time, and flow will continue to drop to close to zero during July.
"The return to restricted pumping will reduce the potential for poor quality water to infiltrate the shallow aquifer."
Unrestricted pumping provides irrigators access to water from the riverbed sands aquifer above their annual water entitlement and with no monthly limit.
Mr Abbott said with river flows occurring since early March, there has been four months of unrestricted pumping and ample water supplies for horticultural production for 2015 and well into 2016.
The Gascoyne River provides the main water sources for the horticultural industry in Carnarvon.
