The flow will be delivered across six days from late January and early February as the water authorities attempt to keep water salinity down in the lower reaches of the river from Rochester to where it meets the Murray River at Echuca.
Salinity levels have been causing potential water quality issues in the lower reach of the river in the past few weeks.
North Central CMA environmental flows project manager Darren White said “flushing” areas like the Campaspe River in summer was key to protecting the health of the river.
“For the past five or so years, irrigation water has delivered the flush as it moves down the Campaspe and into the Murray River,” Mr White said.
“But this year, due to lower water deliveries through the Campaspe, the flush will be managed with water for the environment.”
Irrigation water deliveries are currently lower due to healthy rainfall across the region.
In addition to freshening up the water, the environmental flow will help platypus and fish navigate the river system better as they hunt and search for habitat.
The Campaspe is a vital platypus area.
The flow will also provide a boost for native fish such as Murray cod.
The flow is authorised by the Victorian Environmental Water Holder.
