Snowy River planned high-flow event suspendedDate: 2016 06 10
DPI Water today announced it would suspend the Snowy River high-flow environmental water release planned for Thursday 16 June due to the recent catchment flooding.
Acting Director Surface Water Management, Brian Graham, said the decision to suspend the first of five high-flow events planned over winter and spring was made based on the implications of the heavy rainfall experienced across the catchment earlier in the week as a result of an East Coast low pressure system.
“While the current flooding is subsiding, it was decided that the planned release for 16 June, although having a peak of less than 2,200 megalitres per day compared with natural flows recently of over 14,000 megalitres per day at Dalgety, could potentially impact unnecessarily on downstream landholders given natural tributary inflows are continuing,” Mr Graham said.
“The peak flow rate that was proposed for 16 June will not be re-scheduled; therefore the next planned high-flow event will take place on Wednesday 17 August, subject to weather conditions at the time.
“Although the first high-flow event has been suspended, the same planned total annual volume will still be released to the Snowy River during the 2016-17 water year.”
The remaining planned high-flow releases are:
- Wednesday 17 August – equivalent peak flow 2,236 ML/d for 8 hours
- Wednesday 7 September – equivalent peak flow 2,536 ML/d for 8 hours
- Tuesday 20 September – equivalent peak flow 3,079 ML/d for 8 hours
- Wednesday 5 October – equivalent peak flow 8,109 ML/d for 8 hours
“These high-flow water releases are designed to better mimic the natural flow characteristics that are seen in Snowy Mountain rivers, with the aim of improving the long-term health of the iconic Snowy River.
“Downstream landholders are being encouraged to make appropriate plans ahead of the planned water releases, including moving pumps and infrastructure to higher ground.
“DPI Water will work with the NSW State Emergency Service and Bureau of Meteorology to provide information to the community regarding the management of these release should weather conditions warrant,” said Mr Graham.
