Macquarie Valley irrigators have received a general security allocation for the first time since August 2017.
NSW Water Minister Melinda Pavey has announced a "modest" general security allocation of 12 per cent.
"In the Macquarie-Cudgegong valleys, Burrendong Dam received inflows totalling 161,000 megalitres during August, enabling an allocation to general security entitlement holders for the first time in over three years," she said.
"In addition, DPIE-EES (NSW Department of Planning, Industry and Environment- Environment, Energy and Science) has reported over 45,000 hectares of the Macquarie Marshes, including the critical northern reedbed and Ramsar-listed areas, have been inundated with water."
But Ms Pavey warned of the approaching summer.
"While the recent rain has been a relief to some valleys across the state, the drought is still being felt across the state and the upcoming summer could once again prove difficult for water users," she said.
