BALLARAT Grammar has taken out back-to-back victories in the boys' and girls' open division one at Head of the Lake today.
It was hailed perfect conditions at Lake Wendouree for the rowing regatta, now in its 101st year.
Ballarat Grammar School rowing director Luke Pougnault said it was a great day for the school and all the kids involved.
"Everyone has put in a lot of work and it's shown on the day," he said.
While Mr Pougnault said they knew the boys were capable of winning comfortably, he said it depended on how the crew performed on the day.
"We didn't know we'd win by that much until we hit the finish line," he said.
"Seven of our 10 senior crews won the races.
"Our program doesn't stop here - we keep going full force. We'll be training tomorrow afternoon, getting back into it, and refocussing.
"We've got the Head of School Girls coming up, nationals, and the boys are rowing in the Scot regatta in an eight next weekend.
Ballarat Associated Schools chairman of rowing Gary Palmer praised the event.
"It's been a fantastic day for all school communities to come together for such a positive event like rowing," Mr Palmer said.
"Students are always in good voice and good spirit."
