Issued 10:00 am 25 January 2018
This supersedes the previous flow report issued by the Department of Environment, Water and Natural Resources (DEWNR) on 19 January 2018. The next report will be provided on Friday 2 February 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 6.3 GL/day and will increase to around 6.5 GL/day during the coming week. It comprises:
- ·normal January Entitlement Flow of 7 GL/day;
- less deferred water;
- plus environmental water; and
- interstate trade adjustments.
The flow over Lock 1 is approximately 1.5 GL/day and will remain around this rate during the coming week, depending on weather conditions and extractions. Prolonged extreme hot temperatures have resulted in high evaporation losses and increased pumping, which has reduced the flow rate at Lock 1.
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.
