Held Environment Water

Held Environment Water

From 1 July 2020, the amended Water Sharing Plans in the northern Basin comes into effect. The new amendments include active management rules to ensure Held Environmental Water flows down the northern NSW tributaries, through the Barwon Darling river system. WaterNSW will deliver this part of a water access licence flow allocation that is protected from extraction to improve health of rivers, wetlands and floodplains.

Licence holders will be issued new licence conditions and will need to apply the new mandatory conditions from the date they are deemed as issued.

Changes for Barwon Darling Licence Holders

  • Updated IDECs with a new component that includes ‘daily flow share’ (DFS) to limit impact of pumping during peak irrigation periods. Licence holders can check their new IDEC on the NSW Water Register
  • Resumption of Flow Rules will also apply to ensure first flow after an extended low flow or dry period remains in the water system until downstream flows are adequately established and river connectivity is re-established. This means pumping is not allowed.
  • There are no changes to the conditions.
  • If there is no environmental water present, the existing access rules remain.
  • License holders must continue entering their water extraction into their log book.

Monitoring Announcements for the Barwon-Darling

WaterNSW will issue announcements and flow advice via Water Insights from 1 July 2020. Licence holders must pump in accordance to their licence conditions and approvals in relation to these announcements.

Licence holders are encouraged to subscribe to the Early Warning Network (EWN) to also receive notifications.
