ECHUCA police have said crowds at the Southern 80 waterski event were better behaved than previous years.
Sergeant Paul Nicholl said there were no major troubles outside of a brawl on Saturday.
"It was a pretty normal year, there was no real trouble," Sergeant Nicholls said.
"It was a very good year, better than previous years thanks to good resourcing."
Echuca police had an additional 40 resources from Melbourne to help deal with the estimated crowd of 65,000.
The brawl marred an otherwise trouble-free Southern 80.
Three men were arrested and will face criminal charges after the fight involving about 40 people Saturday afternoon.
The brawl happened at Wills Bend, near Echuca just after 4pm.
Echuca police said there were 61 traffic offence, 23 drunk and disorderly offences, seven criminal arrests, five people caught drunk driving over the limit and one car seized for speeding.
Senior Sergeant Mick Carroll said the arrests represented a very small minority of the crowd at the event.
"It's about par for the course," he said.
"Every year most people are doing the right thing and enjoying themselves and their weekend is interrupted by a few idiots."
