More water will flow through the Thomson River, with the state government taking the next step in delivering an additional eight gigalitres of water.
It maintains the additional water is vital for the health of the heritage-listed Thomson River, and surrounding local communities.
It will also help protect and boost native fish populations, including the Australian grayling, Tupong and Australian Bass, and help increase and diversify plant and animal habitat.
The new water is part of the government's plan to protect the river.
Timing of the water releases is based on scientific advice, including the most appropriate water regime to best maintain and improve the environmental values of the river reaches along the Thomson River.
Water Minister Lisa Nevillle said the Thomson River was the lifeblood for surrounding communities.
"It's too important for us not to act," she said.
"This extra water will mean a stronger and healthier river for the years to come.
"Healthy river flows, better habitat and record fish numbers are all part of our plan for a strong system of waterways."
In line with the Victorian Water Act, notifications are being sent to communities and key stakeholders, and provide an opportunity for local residents to provide feedback.
The two-week notification period will finish next Tuesday, April 25.
The minister will then formally consider the applications and amend the bulk entitlements.
