UPDATE: THE Murray River town of Echuca is preparing for floodwaters swamping Victoria to converge in the northern port next week.

The Murray is expected to rise 2.5 metres by Wednesday, to reach a minor flood level, while several properties near the town could end up isolated.

But State Emergency Service acting operations director Tim Wiebusch said people were sandbagging as an extra precaution, but there was no expectation Echuca would be directly threatened, based on current weather predictions.

Forecast rainfall in the next 24 hours is not expected to impact on flooding around Victoria, but heightened river flows could hit Echuca by Wednesday.

"While we are discouraging unnecessary travel to affected areas, much of the state is still open for business,'' Mr Wiebusch told reporters today.

"Waters have receded in the northeast and the snowfields are open and accessible.''

About 300 homes across the state have been flooded while several hundred more are isolated as a result of the widespread inundation.

As Victoria enters the seventh day of its flood emergency, the suspect levee bank in Wilson Road, Wangaratta, is still containing floodwater that is threatening about 60 homes.

Excavation work to strengthen the leaking levee bank began on Friday morning and will continue over the weekend.

Minor leaking of levee banks around the McCoys bridge area on Friday could affect a few properties if the levee weakens further, Mr Wiebusch said.

SES spokesman Lachlan Quick said crews were on standby in the area with boats and vehicles.

Inundation and local road closures are the main concerns in the northwest towns of Dimboola, Warracknabeal, Quambatook and Kerang where the Wimmera River is expected to have an impact over the weekend or Monday.

The Avoca River is expected to peak at Quambatook, forcing the relocation of the local football final to nearby Murrabit.

"The immediate public health priority for everyone in the affected areas is to stay safe and healthy while the full impact of the damage can be assessed and immediate relief and recovery services are provided,'' Mr Wiebusch said.
