Welcome to this week’s River Ops update,
Collings Trophy Winner 2014
The 2014 award for the best maintained asset in the River Murray System was awarded to Lock and Weir 7 – Rufus River.
Congratulations to John Martin, Andrew Cooke, Michael Ricardi and Sid Lawson. The team’s attention to getting the maintenance of the assets ‘right’, particularly the approach to maintenance of older stoplogs gave them the edge over a very close field.
- Work has commenced on the Mildura weir works this week, removing the trestles.
- Users should expect to see low river levels for the next few weeks.
- The works are a part of a major work to install mechanised gates.
Inflows from the Ovens River over the past week have contributed to the announcement of unregulated flows in the River Murray from Barmah through to the South Australian border (including the Edward River). Within the River Murray system, unregulated flows are defined as flows that are in excess of downstream water demand (including South Australia entitlement), and which cannot be captured within Lake Victoria – the most downstream storage in the system.
Whilst recent conditions throughout the upper Murray system have been reasonably wet, advice from the Bureau of Meteorology (BoM) indicates a drier than normal August to October period is likely for much of the River Murray region. On the longer term outlook, the majority of climate models assessed by the BoM also suggest a weak El Niño event remains likely for the spring of 2014. MDBA’s river operators monitor these climate outlooks closely and consider a range of possible inflow scenarios for the year ahead. These considerations are factored into the River Murray System Annual Operating Plan, with the latest version for the 2014-15 water year due to be published on the MDBA website next week.
MDBA total storage rose by 208 GL this week, with the active storage now 5,897 GL (70% capacity).
