This supersedes the previous flow report issued by the Department of Environment, Water and Natural Resources (DEWNR) on 14 July 2017. The next report will be provided on Friday 28 July 2017.

In this report, for ease of representation, large volumes of water are expressed in gigalitres (GL), while smaller volumes are expressed in megalitres (ML). One GL is equal to 1 000 ML.

2017-18 WATER ALLOCATIONS AND CARRYOVER

South Australian River Murray water access entitlement holders (Class 3a, 3b, 4, 7 and 8) will receive a 100% water allocation in 2017-18. Private carryover will not be made available in 2017-18 due to the positive water resource availability outlook and the risk of spill from the Murray-Darling Basin controlled storages.

FLOW OUTLOOK

The flow at the South Australian border is approximately 11.5 GL/day and will decrease to around 10 GL/day during the coming week. It comprises:

  •  normal July Entitlement Flow of 3.5 GL/day,
  • less deferred water;
  • plus environmental water, and
  • interstate trade adjustments.

The flow over Lock 1 is approximately 10.5 GL/day and will decrease to around 9.5 GL/day during the coming week, depending on weather conditions and extractions.

It is important to note that flow forecasts in this advice are based on the information available at the time of preparation. Advice may change as new gauging information becomes available, or due to rainfall events or changed operations upstream. The forecasts will be revised as new information becomes available.
