No measureable inflow was observed to reservoirs for a third consecutive month during January. High temperatures persisted throughout January, and with little rainfall, substantial evaporation losses from reservoirs were observed. As a result, no increase in allocation has been possible this month.
Wimmera-Mallee Pipeline Product remains at 54% allocation, and Glenelg Compensation Flow remains at 1% allocation. No allocation has yet been possible to Recreation entitlement, Wetland entitlement or Commonwealth environmental entitlement.

The Storage Manager has released its third quarterly Operating Plan Supplement 3 for January to March 2019. This supplement accompanies the Annual Operating Plan 2018-19 and looks specifically at reservoir system operation over the upcoming 3-month period. The Annual Operating Plan and operating plan supplements are available here.
Even with above average rainfall at Grampians reservoirs during December, no measureable inflow was observed, due to the dry condition of catchments. The rainfall received resulted in much lower than forecast reservoir system losses for December, and has contributed to Wimmera-Mallee Pipeline Product increasing by 9% to have a 54% allocation. Glenelg Compensation Flow remains at 1% allocation this month. No allocation has yet been possible to Recreation entitlement, Wetland entitlement or Commonwealth environmental entitlement.
