River Murray Flow Report

Date posted: 22 December 2017

Report #51/2017
Issued 10:00 am 22 December 2017

This supersedes the previous flow report issued by the Department of Environment, Water and Natural Resources (DEWNR) on 15 December 2017. Due to the Christmas New year period, the next report will be provided on Friday 5 January 2018.

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.


The flow at the South Australian border is approximately 14.5 GL/day and will increase to around 16.5 GL/day on 24 December before it starts to decrease to around 14 GL/day at the end of next week. It comprises:

  • normal December Entitlement Flow of 7 GL/day;
  • less deferred water;
  • plus environmental water; and
  • interstate trade adjustments.

The flow over Lock 1 is approximately 8.5 GL/day and will increase to around 11 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.
