The weir pool will be gradually reduced by up to 30 centimetres from July 11.
Murray-Darling Basin Authority river management executive director Andrew Reynolds said Torrumbarry residents and visitors might notice minor changes to the height of the river in the weir pool until it is returned to near-full levels in late August.
“We are lowering the level to reduce the risk of riverbank erosion,” he said.
“Holding weir pool levels steady for long periods can cause riverbanks to become saturated and more vulnerable to erosion from wind and the wash of passing boats.
“Even 30 centimetres is enough to help reduce soil saturation and provide good potential for the growth of native fringing vegetation.”
Goulburn-Murray Water water delivery services general manager Warren Blyth said it was a suitable time to lower the weir pool as it would minimise impact on local activities.
“Although the weir pool level will remain within the normal operating range, we encourage G-MW customers to monitor pumping infrastructure in case adjustments are needed as river levels drop,” Mr Blyth said.
“We also advise boat owners to adjust their moorings and river activities as needed.”
MDBA works with the Victorian and NSW water agencies to keep consistent practices at locks seven, eight, nine and 15 which is conducted annually.
