The partial drawdown is expected to commence on Wednesday 4 May and be fully lowered by around 12 May, before being refilled by early June.

Variation in the weir pool level has been implemented in recent years to assist a long-term goal to reduce bank erosion caused in part by holding the weir pool steady.

The weir pool will be lowered by around 5 cm/day measured immediately upstream of the weir, however larger variations may be observed at other locations due to local impacts.

The river level at Echuca Wharf (82 km upstream of Torrumbarry Weir) will be dependent on both the weir pool level and river flow rates over the coming weeks. The river level at Echuca Wharf may fall as low as 85.70 m under dry conditions.

River pumpers, boat operators and other river users upstream of Torrumbarry Weir are advised to take these changed water levels into account and make any necessary adjustments in response to the lower weir pool level.
