Water Regulator shepherds environmental water flows in state’s north

Media release | 10 May 2019

The NSW Water Regulator is continuing to shepherd environmental water flows released from the northern Murray-Darling Basin last month that is assisting native fish and river ecosystems.

Compliance officers from the NSW Natural Resources Access Regulator (NRAR) are conducting inspections of the releases from the Glenlyon and Copeton dams, as the water makes its way along the Dumaresq, Macintyre, Gwydir, Mehi and Barwon rivers.

While the two releases are expected to meet in the Barwon River at Collarenebri in the next few weeks, the exact distance the flows make it down the Barwon cannot be predicted due to the extremely dry conditions.

The Northern Fish Flow will see between 27 and 36 gigalitres released by the Commonwealth Environmental Water Office and the NSW Office of Environment and Heritage, and is supported by a temporary pumping embargo in place on the Barwon-Darling from Mungundi to Tilpa.

NRAR’s Chief Regulatory Officer Grant Barnes noted that compliance officers are undertaking proactive monitoring in the Border Rivers area as they shepherd this important environmental flow downstream.

“The onus is on the water user to ensure there is no restriction on their ability to pump before they do so. Most water users follow the rules and meet requirements, however we won’t hesitate to take action where we find instances of non-compliance,” Mr Barnes said.

More than 1000 km of river habitat will benefit from the flow, which will support native fish struggling to survive in isolated waterholes.

Along with inspections, the flow will be monitored using satellite tracking.

“Compliance officers have their ‘boots on the ground’ and are supported by ‘eyes in the sky’ as we take advantage of a range of technologies to support our work,” he said.

NRAR compliance officers were on the Mehi River this week as the head of the flow arrived, making its way into the dry riverbed and inspections will continue throughout the month.

The flows won’t just benefit fish – they will also provide relief for river communities, contributing to town water and basic stock and domestic water needs. They will enable some recreational river use and support fish species that are culturally significant to Aboriginal people such as Murray cod (guduu) and catfish (gaygay).
