Reservoir levels

Keep track of reservoir levels and water use information here.

The Western Water region has two main water storages, Rosslynne Reservoir and Merrimu Reservoir, both of which are managed by Southern Rural Water. These reservoirs supply the Melton and Bacchus Marsh (Merrimu) and Macedon Ranges and Sunbury (Rosslynne) districts. Western Water manages a number of smaller reservoirs in and around the Macedon Ranges. The region is also connected to the Melbourne water supply which can be used when local supplies are low.


Surcharging and pre-release policy

Western Water’s surcharge and pre-release infrastructure associated with its water storage dams and reservoirs is very limited, and as such Western Water is not in a position to undertake any surcharge or pre-release prior to flood events.

Western Water’s storages are equipped with spillways which allow  flood waters to spill from the storage if it is at full capacity. Western Water will monitor storages during and post flood events and will respond as required.
